Using my website to make templates available

I create templates using Microsoft Office products including Word, Excel and FrontPage. I would like to make these inexpensively available.

I write internet content for several companies. One site (constant-content) does nothing more than store the writer's articles until someone wants it for their website. When the customer purchases it, constant-content pays me (taking their cut of course).

Does anyone know of a website that would support this type of thing? I'd like to post my templates for sale, say $2 each. But would like to concentrate my time on building templates and writing, not website maintenance.

Thanks,
