2D plan (AutoCad / BricsCad) of a backyard garden.

I am looking for an architect or landscape designer who can create a 2D plan (AutoCad / BricsCad) of an existing backyard garden ( average 2000 square/foot). The garden is crossed in its center by a small stream with a waterfall at its origin which will have to be preserved. The goal is to improve its current presentation according to the indications that I will communicate to you. The work will include giving away the CAD file so that I can later do the 3D visualizations and site planting. 1 or 2 revisions will be necessary and must be included in the project. More work will come later if good communication takes place. I will choose the freelancer in the next 24 hours, thank you.
