You can research what affiliate programs are already out there and try to compete with their commission rate. Try to get listed in affiliate marketplaces like ShareASale or CJ. I don’t have experience actually running an affiliate program but I personally look for good commissions and a company with a solid reputation with products that can actually help my readers. Make a list of relevant websites/influences that fall within that criteria and reach out to them about your affiliate program. I know it’s broad advice but that’s why I see other companies do – they often have affiliate managers that are constantly working on business development.
Considering that you have a finite amount of time, passive income should make up a large part of your work. If you're serious about generating any semblance of income online, then passive income should be one of your sole goals and ambitions. Why? Wouldn't you prefer to do the work one time and get paid repeatedly as opposed to relying on your time to generate that income? Invest the time at the front-end so that you can reap the benefits on the back-end. This means putting in a bit of sweat equity and not getting paid today. Rather, you'll get paid somewhere down the road. And you'll continue getting paid whether you keep building that passive income stream or you stop. 
I am a STAM working 3 jobs… all part time and from home… (can u believe it?) But really, I started with the mystery shopping, and that was OK. The positive was you get paid, the challenge was not frequently and sometimes needed to wait a month for payment to be transferred to the paypal account. Then I became and infant massage teacher and love this. REDTENTSALE is my Ebay store, I sell so many various items I find from wholesellers and it’s nice, I do this when the kids are asleep; anyone can… very manageable and nice “but light” income. I would say the one by far that is taking me places is Real Estate Marketing.
To make money from affiliate marketing, you need to ascertain that the product has a high demand. No matter how much efforts you make, you might make little or no sales, it totally depends on the demand of the product. You need to know if it is what your audience really needs. If you manage to get a reasonable amount of traffic on your site, then you can run a small online survey to get input from visitors.
For example, if you buy a $100 suit… perhaps you could rent it out for $25 for the night/weekend and someone locally is interested in just a cheap rental (because they don’t need to own a suit for the one or two times per year they wear one). After four weekends of renting the suit, it’s paid for itself. Now, whenever it’s rented out—you’re profiting for the remaining life of the suit.
While I was doing WordPress speed optimization I noticed lots of people needed it, but very few people supplied it (there were a lack of services and tutorials when I researched Google). I also knew hosting was the #1 factor of website speed factor and these companies paid up to $200/sale. Hosting is a competitive space but the commissions and lack of supply enticed me.
22. Advertising – This is definitely the most old-school way of earning money with a blog. It’s also starting to become the least common way. You can sell advertising spots directly on your site or you can sign up with a company like Google AdSense or Media.net. Either way, you won’t see a whole lot of money from ads until your views are well into the thousands each day.
Research other listings in your city on AirBnB and see what the going rate is for a place like yours. You could also just rent out a private room as well or even a bed in a shared room. In fact, that's how AirBnB got its start. However, you might find it hard in the beginning without reviews, but as long as you take really good care of your guests and provide a lot of value, the reviews will eventually come rolling in.
If you're serious about making money online, start a blog. Blogging is one of the easiest and most sustainable income sources. As long as the blog is setup the right way, in the right niche, with the right content targeted at the right audience, and the offer is complementary to the content, you could make a tremendous amount of passive income from a blog. 

I would probably rely mostly on Amazon as an affiliate – talk about products you use while using an affiliate link. You don’t necessarily have to focus your entire content on reviewing products, just mention them in your articles and your experience with them – how they helped you. Amazon is good for obvious reasons – super high conversions and most products already have lots of reviews which is very valuable as an affiliate.
Transcription is one of my part time jobs. I can do it conveniently from home and many of the clients are trainers or speakers. Having money and needing transcription services doesn’t imply you have a secretary. At my full time job the closest we have to a secretary is the CEO’s assistant. She books flights, plans travel, schedules meetings, transports his children, and helps with home renovations. She doesn’t have the time to sit and transcribe work when the CEO can send it to a company or freelance agent for a few dollars.
