Floor plan consultation, plans for addition to home, interior design and renderings of key interior spaces

Hi there. I am first in Freelancer, but i wanna choose my correct candidate. This will be long-term relationship project. I am planning a major home renovation including an addition of 100-150 sq feet of space to the back of the house. I see this project having 3 phases: 1) Floor plan/layout design--this should be relatively quick 2) Actual drafting of the plans and renderings--this is where I imagine most of your time will be spent. 3) Verification from a structural engineer--this will be outside of the scope of the project, but after I receive the plans from you, I will take them to a structural engineer who can look at the plans and the house, size any beams and make any final site-specific adjustments before I submit the plans to the city. I would prefer for the final draft to be in Sketchup so that I can go back and make any final changes to textures, finishes, etc, but am open to something in Revit if you think it will produce superior results for my goals. What I will provide: See attached a Sketchup file that is basically just the layout of the exterior and interior walls with a rough sense of where the current fixtures are. The walls are accurate to within a few inches. I can also provide photos and videos of the house to give you a sense of its current layout and state. Floor plan consultation -Recommendation for where/how the addition should flow into the existing floor plan, including any changes to the existing floorplan for a more open feel -Recommendation for kitchen layout and location of key fixtures, bearing in mind the location of plumbing -Recommendation on Master Suite Layout Drafting -Need detailed plan that will be usable by builder and city for permit application -Should include a foundation plan for the new addition. -Plans should include schedule of openings for verification by a structural engineer -Plans should include rendering of key spaces including a kitchen and 3 bathrooms and a furniture layout for the living spaces. My Maximum budget for this is 400$.
