CAD assistance for interior design floor plans

I'm an interior designer that needs CAD assistance to make some revisions to a floor plan . One version would show the suggested revisions as an overlay to the existing and another version just showing the revised floor plans. Revisions are actually fairly minor. Upon completion I expect to have a reflected ceiling plan and some bathrooms and kitchen elevations to add to the CAD set. High level for initial client review not for construction or bidding. Working with an architect on the project but for cost and speed reasons looking orr an alternative for some of the plan needs. Screen shot of the plan attached. Would like the ability to converse with the freelancer and not just communicate via email and text.
