Wall Flask

I have a product I'm trying to get manufactured and the company that I'm going through gave me a ridiculous quote to take my rough draft design and turn it into a professional design that is ready to be manufactured. The product is very simple its a water bottle for your wall basically that consists of a hard plastic bladder with a lid and a camelback-type hose and mouthpiece that comes out of the bottom. I would also like to have an indention in the back that can hook onto a command strip hook. The flask will hang on the wall via the command strip hook. I will attach my rough draft in a .stp file.
