Hi, am architect with 9 years experience designing mostly working spaces, I could do your design with CAD plans, furniture selection and 3D visualizations.
I estimate a day or two to create 2-3 draft proposals, another day to polish and do corrections, and 2-3 days to do the interior decoration details and 3D visualizations. Total estimated job time 5 days.
At the end I will provide you the CAD floor plan, and the 3D aerial visualization plus one or two renders at walking level.
I could start working on your project on Thursday 17 after finishing another 3D visualization job.
