Assistance with Interior Design Project

I have been appointed a large interior design project but I have a very busy workload at present so looking for some assistance from an experienced Interior designer who can assist with designing, space planning, 2d & 3d floor plans, with accurate scaled measurements. Possibly realistic CGI/Renders but could outsource this if needed. To start with first room and see how we get on to progress with further rooms. I have images and ideas of the space I want to create, and scaled architects' drawings.
Please note I am looking for an interior designer to work on space planning and creating visuals. Not just someone to render my designs.
I have enclosed examples of the standard of work I am looking for, this is not the project.
Need to be available to tweak plans/designs after I've discussed with clients.
