Firstly, I compared rates within the spreadsheet to the rates provided in the description. I fixed a few typos in the rates column. Then, I checked the formulas and ensured those were correct. After that, given all of the limitations, I ran numbers for a few possible scenarios to fit the budget and client constraints and decided to suggest to the client to eliminate the Korean language from the project budget to stay within the approved budget of $10,000. The math and explanation are shown in the attached spreadsheet.
