There was talk about a marketplace in this thread and I think the natural place for something like that would be on hex.pm 
It would also give the Hex team another avenue to fund itself, by means of taking a small commission from successful jobs (they could act as the intermediary - so take the fee, then when the project is complete and the payer happy with the work, release the fee to the developer minus the commission).
Alternatively, we could host a Marketplace section here - although without being involved in the payment process/commissions etc. Discourse has one on their forum.
