How much is the salary of the developer you're looking for? Marketplace won't be the suit section for this person finding fit for the person.
Give it a try on
Marketplace (Altcoins) because it's like you're paying in tokens, don't you?
It's kinda impossible to find a blockchain developer these days that the payment will become on altcoins and their altcoins are not so popular at all.
The best section would be under Bitcoin Forum > Economy > Marketplace > Services, if OP wants to finish the issue with no problem and they are serious about the project at all, they will gonna spend a good amount of money at all.
