Since you have a current scripter, you can refer them to this module, which would both save you money and save them effort: Making a combat game with ranged weapons? FastCast may be the module for you!
Hiring a separate scripter might cause you trouble, not because he is bad or anything, but different people do things differently, which means different techniques of handling stuff, and basically a different mindset. Having a single skilled scripter is all you need.
Of course if you choose to hire someone after all, I would be happy to apply, here is my Discord: AlvinPolys#0001 Can discuss more over there and show previous work etc.
