Most Engineers get paid for this. Around here the average is about $97.88 per hour. I would guess that what you want will be in the vicinity of 10-67 hours, depending on diagnostics needed. Maybe someone will volunteer to do the math for you?

Sounds distinctly like a programming lab in a college class. Give it some thought and post your ideas, then people will comment on it. It sounds like a simple latching circuit to me. Take about 30 seconds to write.
