Do you already have a Server to run these Scripts ?
Which Coins do you wanna Support ?
How many developers do you need ?
1) Not yet, gonna need the dev to develop it on his server and then I'll buy anonymous bitcoin hosting
2) Bitcoin initially, but I hear there are clever ways to integrate multiple coins using stuff like Shapeshift. Am I correct?
3) I don't know, as many as it takes. Preferably I would want to work with only one or two. Again, I am not the slightest technical so I would leave this decision to the developer I choose to trust with the project.
