PCB design group

Hello - just wondering if someone here would be willing to look at a board I've got and modify it to work with a 48v / 8.3A / 400w power supply (right now it handles 36v/9.3A/350w).

If someone could take a look at it and give me a price, it should be a simple job since nothing else needs changing besides a few components.

Here's a link to the file (on megaupload.io). You can message me here or email me.

Thanks!
