Custom Cards
 

Does anyone here have any experience making custom cards? Any suggestions as to the easiest way to make them? Cheapest?

I have a guy that can create one sided cards for me but I think I'd like to have a go at making two-sided cards. I can find templates online and I imagine I can find a program to mock them up but:
what's the best program?
Should I print at home or take them to be printed?
Where?

Any tips would be welcome.
I've got about 1500 players who don't have cards that I'd like to make cards for.
Thanks
