Need T-shirt designs for vending machines biz

I need 5 FINAL designs for T-shirts. The designs should have several preliminary ideas to choose from before being accepted and rendered into the final print ready design. Designs will be large as if to put on the backs of t-shirts. Topic will be "vending machines service." (snack & soda, vending machine service, refreshment service, snack machines & soda machines, etc..) I only want designers who have a similar design style to the attached files and very professional. After successful project, I have lots of other design work as well if parties agree. Thanks
