Forms are one of the hardest things to deal with unless you have the software, web space and capability to code. Wufoo makes it easy.

The site uses a pretty user-friendly form building tool. Once you're done, you have the option of using the code they provide to embed the form into your blog or web page. The form allows uploads as well.

If you don't have web space, they will give you a URL to the form which means that you don't need a website just to make the form available.

I just re-did my website's contact page with it this morning - worked great, and it looks a whole lot better than the one I had.
