Lot of realistic replies in here so far. I have to concur that starting out with a paysite isn't a good idea, as tempting as it may be to "just go for the big bucks". There's too many who try it without a solid understanding of marketing and without knowing how sites get promoted via freesites, avs sites, tgps, blogs, hubs and so on.

It also helps if they have basic web skills. I've done sites for people that didn't (and still don't) know how to ftp to their domain. And it sure doesn't hurt to have some understanding of creating the html pages and/or minimal graphics.
