Campaigns & Settings on the Marketplace

I'm wondering if people would be interested in extended campaign materials on the Marketplace.  Particularly at the moment, I have a group going through a campaign from Level 1 to approx. 17 using D&D 3.5E rules (which could be easily adapted for Pathfinder players). Would people like a long Campaign like that on the Marketplace? Would people be interested in new Campaign Settings on the Marketplace? Just want to know this sort of stuff before I go around trying to OGL-ify a whole heap of existing material. Thanks, Andrew

If somone was willing to sell a pre-built Adeventure path with all the maps uploaded, tokens created(stats imported) and notes on the GM's map so all I'd have to do is read up on it once and then run it, I'd love it.

That sounds close to what I'm making then.  So there's one person who might be on board. :P
