>>>>. It really does have potential
Be aware that potential is the reason people will buy the site, but it's not the reason they're going to pay more for it. The purchaser realizes the return on the potential, not the seller.
Expect a price based on your current income. If you want to increase the value before selling, increase the income by realizing the potential. Otherwise expect to use the potential simply as motivation for the purchaser to buy.
I wouldn't start selling a web design business on the web, I'd start by trying to sell it locally. Call some local shops, see if they have an interest, show them the revenue and the untapped leads.
