i like that break down. depending on structure, and skillset, we may be able to have founding folks "buy in" in kind rather than with cash. we're going to need cash, but we're also going to need a decent bucket of skilled labor. i.e. an architect or electrician could pay by providing x# of hours of service to the group.
i'd encourage this to be based on skilled labor industry billable price point *.5 so that an architect who typically is billed (not earns) at 100/hr would have to put in 200 hrs of *skilled* volunteer labor to get a full 10K share. i.e. if they're in final design meetings that counts, but sweeping the floors and helping do demo work only earns say the ... $10/hr credit? for donated labor? that way jimmy q maker w/o specalized skills, but is useful with tools can say buy a partial share with 100 hours of work, but items we'd need to pay skilled folk for we can get at discount, but they'd be invested in the project.
10K gets you a major share, a permanent seat on the advisory board with 10 votes and ownership stake, 1K a minor which gets 1 vote on advisory board, but not a *seat* on the board per se. say annual membership is 200$ after 5 years you get 1 vote, or once you contribute that much.
