help with DIY invites

I decided I would order my pocketfolds from cards and pockets and assemble the invite but I am really NOT creative and to lessen the stress I would rather have a printer do the actual invite. Has anyone done this and if so who did you use??? How do I do this with the inserts too???

I have thought about ordering one from online but I cant find one that I like and its esp. hard since i want a square 6x6 invite. I basically want to design it somewhat and have someone else print it.

TIA!
