Hello,
Just found this thread. Good work!!!
I would recommend to buy components (North America) in :
Electronic Components from the Best - Future Electronics
or
Avnet Electronics Marketing - Electronic Components Distributor Services, Datasheet PDF Download, Part Number Search 4.5 Million + Components - Avnet Express
Digikey and Mouser are expensive.
It doesn't make sense to buy controller board on the eBay and add it to hand-made PCB. Better to use one PCB board for all components.
To make a high quality PCB in few hours at home use :

Print PCB layout on LaserPrinter on trasparent film. Then expose 10min under UV (I use regular energy saving fluorescent bulbs) and develop in MG Chemical solutions. All information is available on /www.mgchemicals.com
Power section layout is bad. Look at the attached tutorial from Mariss Freimanis for details.
I will probably try to make this drive for myself to test my small motors. PCB has to be redone in very compact form using CMD components.
OhhhhNeed to recover my PCB design sills. Didn't touch Altium Designer and Eagle for more than 4 years.
Another option is design a board and place it with 4PCB or other manufactures. With >20 boards it can be a very reasonable cost which we can share.
Just my 5 cents.
