I'm using joomla as well since the biginning. Best choice you got is the learn how to create a template and once you are familiar with it you can create something on your own. The bad thing about templates is that they are template. Someone created it and the structure the css and everything is made under the creators concept. I know it my be longer, but if you want something toatally unique than you should try to scout a clean template and delete almost everything and build it up your own. It does only work if you have some practice in graphic relates programs.
Regarding the usage for free.. I made a flash for my site (which isn't fully ready yet) and made a poll to check if anyone's interested, but I think this community shares knowledge with you and answers your questions, but it's not the right place to offer something where you want some money in exchange. Btw.. I like the idea of "template usage for a link to site" thing.
