Saul - we could probably handle that. Our server has around 1500G of bandwidth/mo and we're not running any where near that now as most of the client base is small business. As it stands right now, I see no need to be charging for any additional bandwidth. If this site grows and starts consuming more, I could see where we might have to.
I could also envision a model that if we got enough referral business from the site, we could run this site for no charge. If it helps in the interim, we could also probably run you for free too.
