Very nice kaselit! This will be a big push for the rai development. Have you already get in touch with clemahiue and to other devs about this plan? BTW, Is this 20 bitcoin reward came from your own wallet? No contribution from the original devs of raiblocks? ( Sorry for all the questions, I'm/We're just curious about this since the amount to be contributed is big ).
You can also replicate the issue in some freelance websites like xbtfreelancer.com . Maybe you can find good C++ programmer in there.
