Why focus just on attorneys? Why not make it more generic for any type of consulting that would fit this type of model? Accounting/CPA/Taxes seems like the next fit.
How do you plan on competing with Avvo, RocketLawyer, and LegalZoom (all of them also offer attorney referral services)? Or are you planning on not competing with them and serving more of a niche market?
I think focussing specifically on facilitating the initial consultation means the product can create a better experience for people looking for legal advice - scheduling, video chat, free consultations, and a bunch of other little details. We'll leave the DIY document creation to others.
