Autocad drawings

I m an architect. I need Autocad drawings of elevations drawn up from an artists sketch of a building to which I’ve added measurements for a simple listed building consent. The external signage for the building also needs to be shown on the elevations of the building.
It’s a fairly straightforward and simple job for now. If all goes well I will be looking for further input.
I would like the work to be done preferably with somebody UK or London based.
