House floor plan with facades

We are a new project home building company in Australia and are looking to design our model portfolio of standard 3, 4 and 5 bedroom homes. Our range will include 24 different floor plans in a range of sizes from 16 squares to 40 squares with each home having a choice of 6 different facade options. I am looking for a quality architect to help design the range of floor plans and the 6 different facades for each floor plan. Before I award the entire project to a Freelancer, I would like to start working with 3 or 4 different Freelancers on the following SINGLE drawing (your bid should be for this ONE assignment only): "A 4 bedroom home with two living areas and double garage between the total size of 202m2 and 212m2 including outdoor area. I am looking for one floor plan and six different facade options. Your drawing will be presented in CAD format with measurements and to the standard of the attached files. These two sample homes design files will give you a sample of the features we like in our homes as well as a head start as they are already in CAD format." In addition to the above, let me know if you can do 3D renders to the standard of the attached 3D render (Amber Metro) and I will pay EXTRA for you to do this as well. The person I enjoy working with the most and who understand Australian home design will be awarded the other designs. Good luck!!
