Help! Question about new domains & free hosting

So I just registered about 20 long-tail keyword domains that I can reach google page 1 with. I'd like to get free hosting with Wordpress or some other domain that I can easily set up landing pages on. Who should I use? I want to use some SEO plugins, whitehat and blackhat plugins, etc.

I know getgreasymoney has a MU site and it's pretty good -- I just want something 110% reliable. I'm not saying their site isn't, its just that I want a long term stable solution.

Thanks!

I suggest you the biggest companies, like HostMonaster, BlueHost, GoDaddy, etc...
They are reliable... btw, always read the contract before buying.
