seems good to me.  however, you might want to buy vB outright instead of leasing at $85/year.

i see owned licenses being sold frequently. the problem is people do not read or understand the Jelsoft's stipulations regarding selling owned licenses.  if you bought an owned license at the outset, you stand a high chance of reselling it and recovering something should your forum flop. if you lease the license you are guaranteed to get nothing back on the license fee as leased licenses are not legally resellable or transferable.  also, if you buy the license, you can  use it on another site later if you decide to have a go at another forum, or add a forum to an already developed site.
