Interior Design of 1900 sq ft flat with available resources in the city

As a homeowner, I am seeking an interior designer to help me redesign my 1900 sq ft flat. I am looking to create a contemporary aesthetic with the given resources in the city. I am open to suggestions when it comes to col0ors, as I have not determined a specific color palette. My budget for the project is less than $100. It will take a maximum of 5 hrs of discussion.
