Depending on what stage of business you're interested in and how you see your own role in the project, I might be a potential partner for you.

And if not, I might be able to identify relevant prospects or add value to the enterprise (depending on what it turns out to be).

You don't need 100% of the skill set, provided you can ask the right questions, proceed slowly, find reliable partners with relevant talents or include them as part of team-building.

Buying an existing website outright would be the wrong course of action unless you are retaining the webmaster as a partner or employee ... or unless you're bringing in a capable partner who advises you that he can take over the management of the site.

There are probably many online businesses that have stalled and could be expanded with outside help.

And there are an equal number of startup concepts that are actually very straightforward to implement. With patience and good execution, they could be built out profitably.
