I have a real passion for helping people in this area and currently do it for my friends , family and co workers. I always receive great feedback.
Pick a memorable, intuitive name that fans find easy to recommend to their friends on the phone (voice and text). Consider the name not just in the abstract but in terms of a domain purchase.
I keep waiting for somebody to use Pennies.net for a site like the one you describe. Full disclosure: I own it. But I'm pointing to it mainly by way of example and not as a sales pitch.
Take some time to plan for a cohesive brand identity. Your goals, site design, and written style should match one another and offer something clear to visitors.

Good luck!
