Internal shop redesign

We're undergoing some shop alterations for a small ice cream parlour- We've previously had a friend help with some initial CAD drawings, helping to design the interior or the shop, and roughly redesign the small outdoor courtyard. However, our friend is no longer to help, and we need someone to finish off the plans (I have the CAD file).

We're working with a very small space, and the goal is to fit our machines, freezers etc. into this space in the most optimal way, leaving as much space for storage as possible, so some inventive thinking may be needed.

Any creative ideas are especially welcome- It probably won't deviate too far from the initial drawings- we have all of the measurements (you can probably use the existing CAD file as mentioned), but we just need a final signed off plan so we can share this with our builder to implement.

We've already put in for our planning permission from the council, but as this is redesigning the inside of the shop on the whole (some advice on the courtyard would be appreciated as mentioned), then we're good to go as soon as the designs are finalised.

I don't envisage this taking a long time, but we would want the final file by the end of September ideally.
