PCB board modification

I need to modify DC power supply part in the board. Now board is working from 6-7 V DC input power source. I need it to be working with 5 V DC input. You need to modify schematics and board file in Eagle software and send me gerber files.

I will order PCB and solder the board. If it is working, than I will release the funds. If it is not working - I will send you the board to inspect it and find the problem.
