Need to create sales page and optin box to "start" growing list.

I'm learning Ithemes Flexx right now and may be able to figure it out, but in case not, suggestions on finding free templates or second choice paid for.

Familiar with www.fiverr.com for outsourcing? A friend was pleased with movie they did but she paid $15 as more complex. She was happy!

Would you get separate domain or your suggestions? Or, should I add in to to an existing website, although I may not be using the existing one I have later on.

I'll use aweber.

Thanks.
