I would rather partner up with a developer that is passionate about the project and would be willing to work on it sharing the premine.
It is not as easy as that.
You will still need capital for them to work as full as they can. What if the project did not click? What happens to all that time and effort that they have done? You are the one in need so better be ready for some payment for your team.
It is okay if maybe you are friends or relatives but that doesnt happen much.
Maybe look for an investor first for the project to be backed up.
