T-Shirt Prints?

Hey guys,
I run an Italian Club at our school, and this year for a change, we wanted to get club t-shirts. I’ve never really done anything thats meant for print, never mind a shirt, so I’m at ground zero. I think in the end we’ll need around 40-50 shirts, and we really dont want to break the bank on them.

So my questions are:
Can anyone give me the names of some quality shirt printers?
Can anyone give me an estimate as to how much this might cost?

I also have some mockups that we seem to like as an organization, anyone wanna take a look and tell me if this is feasible? I’m assuming it is, but I’d love to get your imput on it.
