About the payment, we can figure out a btc payment via escrow. There is a John K person here that already solved a task like that.
About the payroll, Kate, we can eighter share the profits based on initial payment (budget of a person), in percentage, or we can set-up a funding entity on btct.co and have shares which bring an incentive (dividend) every round. We can also trade those shares later. i see many BFL devices for sale besides Avalon. I'm not sure if we can raise the funds for an avalon (roughly $30000). What do you guys think? Shall we raise the money first and then think of options to spend it?
