Bitcoin flash transaction sender in 2DAYS

I am looking for a programmer who will make a program for me - a bitcoin flash sender transaction. I would like to contact people who have already done something like this or have such a program on their computer. Lots of people try to cheat on this program, so before paying, I would like us to do a test that eg Transfer 0.2btc. I care about time, so if you have something like that working, we will definitely work it out!

I need to have it ASAP
