Good afternoon from Athens.
Your project is not so much as qualitative work so as quantity work (78 Algebra problems!!!). You need do understand of course that solving these problems and digitizing the solutions in a Word file or a pdf file is time consuming. Therefore, I suggested that it can be done for 30 $ and within 7 days time, that is approximately 10 exercises per day. So if you believe my bid is good, send me the 78 problems to have a look at them and start ASAP. I'll be looking forward to your response. God bless you and your family.
Respectfully yours,
Ilias G. Patelakis
