Sure, it'd be preferable to have a full fee schedule available, for cases where it's needed. But, given that using a concierge service is perhaps the definitive case of spending money to conserve time; given also that this is a side project which has suddenly blown up in its creators' faces; and given finally that said creators appear to be working unbelievably hard to scale it up and out to meet the demand they've discovered -- given all that, I think it's pretty unreasonable to shit on the people who've made concierge service cheaper and more accessible than ever before because, in scrambling to meet unexpected demand, they have yet to get around to polish. Give them a month or two to get everything shaken out, and if they still haven't put up any fee information, then go after them. Until then, calm yourself; you are, after all, free not to use their service, if it fails to meet your requirements.
