Research selling prices of items similar to yours. Look up completed sales or current listings of items similar to yours. Find the high- and low-end prices, and price your object around the median price level. If you want your item to sell quickly, price it at the low end. The condition of the item also affects the price. Items in poorer condition should be priced at the lower end. Also, consider how many listings there already are of items similar to yours. If many similar items will be competing with yours, you may have to set the price lower to get the sale.
One more thing, In order to make money with sponsoring, you need to advertise which can get costly. I try to do as much as I can by posting ad for free. Google search for “free ads” or “free ad post” and you will get hundreds of places to post a free ad. Some work quite well, some don’t. But they do work. I also have great places to find leads for free and even profit from it. Here is some places to find free leads.
Whether you have a website or are still dreaming up ideas for a blog, you can also look into affiliate marketing. With affiliate marketing, you partner with brands and businesses within the content of your website. If you mention a product or service, you link to that produce or service using a unique affiliate code you received when you signed up for that particular affiliate program. From there, you’ll make money any time someone buys a product or service through your link.
