or if you cant answer that question, maybe you could tell me whether it is worth developing a site if i had the appropriate skills in php and photoshop.
In generic terms, its hard to answer this question. If you have a good idea, and domain name, then you can expect that the more you develop the site, the more its worth. However, as seeker was saying, a badly developed website might not sell, or sell for less than just the domain name. On the other hand, a well developed, awesome site, about something no one cares about, also might not sell.
Spend some time looking through the Platinum->websites for sale forum. Lots of nice sites selling for low $, high $ or medium bucks. A few sites not selling at all, poor implementation, simple template mods, or the site's concept or idea was a "labor of love" by the developer, and does not apply to the people who buy in this forums. There's a couple of GREAT sites in there that haven't sold, but you can see where huge amounts of time and skill have gone into their implementation.
To turn your question around. If you feel you have good skills, and want to build a portfolio, then I'm sure you could advertise your services, and get people to pay YOU to develop THEIR names and ideas. Sure, this forum can be a tough crowd, but that's because people here are more or less "in the business". Maybe you can develop sites here, but sell them elsewhere to the general public. Heck, if you work cheap, you can develop some of my DNs and ideas...
Okay, if your question is really not as generic as you've made it to be, and you actually are talking about a specific domain name and site idea and whether you should develop it, then you need to air it out with your peers or your support group. Maybe ask for help publically, and continue the discussion in private with whomever responds.
But remember, keep in mind where the advice is coming from. Everyone's got an opinion, but not every opinion should be followed.
