Graphic design - project layout/ construction design of a small shop

I am looking for a graphic design artist that could help me put together a visual display of what i would like my shop to look like - it would be inside of a warehouse so it is more open concept design in about 850 square foot of the warehouse. It will also have a trolley ( which i have graphic images of ) within the shop area. basically a build out from this mobile shop. I drew up a mock of the space, but a warning it is much like a 5 year old drew it. The things i would like If possible - dimetional so you can see the front and also a side view. The whole shop area to be covered by a floating arbor with greenery kind of hanging from it.. 12 foot off the ground The trolley to sit at the back with small decks built where the doors open for people to get into the trolley shop - the trolley is 11ft 8inches tall with the sky light on its roof. It is 30ft long I would love matching counter top spaces build to each side at and angle at the trolleys front and back. the one at the back would be the check out. Two counters, same 6-8 foot in length, 40 inches high, matte black, with matte black detail of some sort just to mark it, and then cement counter tops. the counter at the front of the trolley i would like to match this, but would be used as a very modern floral counter. The displays all over the other square footage will be a mix of matte black, iron, nice custom wood for the tops and some old furniture painted matte black. I have attached quite a few photos of what i see. I would love to work with someone on this if possible!
