Sounds wise to me.
(Tired Saturday brain dump coming:)
However, i agree with @steve_pitchford that I don't see enough of a planned business here. I think you should do more pre-launch research and market testing before going to the lengths of incorporation and a dedicated bank account in order to launch something real and institutionally 'safe'.
To quote Steve Blank: "Get out of the building" - have you spent time asking people on both sides of the transaction about that they want? That's a good enough first pass and needs no live site at all; don't wait for people to organically arrive or find the site via marketing and sign up as your feedback - you'll be waiting too long).
You've got another marketplace here, raising a few thoughts:
1) this one is pegged at a significantly higher spend (and therefore a harder sell / greater innate friction) than Storklancer. I, too, expected the MVP to be that - this one was a surprise This is going to be harder work, even if the commissions you make are higher. I doubt this is a 'build it and they will come' thing.
2) marketplaces are 'so hot right now' - but that doesn't mean they are easy. Getting enough supply to meet demand and enough demand to encourage supply ('market liquidity') is a significant challenge. Marketplaces can stagnate quickly and are hard to pull back. Do you have connections in the construction industry tonl seed at least one side of things?
3) that name - i can't say it, I can't type it after briefly seeing it, I don't know what it means when I hear it. MyBuilder, for instance, doesn't have tgiuse challenges. I'd rename it.
Sorry to sound so down on thibgs, @SylarRuby - it's GREAT you're shipping something. What you're doing at the mo definitely reminds me of me
