Actually blockchain is really new sector in field of programming so there are not many blockchain experts and the one who are out there are trying to capitalize current situation by creating alts and conducting crowdfunding to collect millions for their world tour. Look at vitalik for example...
So it is hard to calculate what could be the hourly rate for those experts, they are currently enjoying millions creating their own projects.
I am afraid that the self-proclaimed millions may vaporize soon without community support.
