Where can I print on Long Island?

I am making a few of my own signs. (example:Signature drink sign)

I made them 5x7 so I can put in a cute picture frame.

I found 5x7 paper but Im nervous to print that myself in my printer.

Is there anywhere I can go that will print cardstock?

my mom did our engagement party invites at Kinkos and they were really inexpensive
