Ok I'm just throwing this out there, if anyone is interested. I have a couple servers around and can host as many sites as is needed, the only thing is I'm not a big fan of the SEO side of things. What I can do is get a wordpress (or other maybe?) install set up with all the standard plugins, etc etc. Once that's complete, I can clone this setup any number of times, it's all just a matter of picking domain names and pointing them at the server. This being a Joint Venture, I'll be asking you to provide the domain names while I can provide the nameserver and hosting. I'm in favor of making mass sites, I'd like to aim for 500 total within the year, it's just waiting on you to decide how many niches and domain names you want to take from my block of 500. Any takers?
