Most people who design webs don't like to use other peoples templates, they like to design their own. I, being a web designer, have never paid for templates because they are usually too restrictive to the page layout.
I have however commisioned professional cartoonists to produce characters for use on specific websites that won't be used anywhere else.
There are far too many websites providing FREE templates, backgrounds, graphics. You would have to be a very special type of person to think you can make money.
I think you are just after people paying you for sticking a few graphics on your site (probably not even your own work). Your previous posts are always about making money like your life depended on it!
Why not do your website with everything for free so people can see the quality of your work. Maybe later on you could charge.
Don't do drugs kids. There is a time and place for everything. It's called college.
