Hello, I am an electronics engineer student, I have used these equations before in an electromagnetism course, and I know that I can have your work done easily.
I ask you for 5 days to do the project because I can't stop working on your project until saturday. If you need it to be done fast, you can tell me your deadline so I can search for a partner to do the task (But that may cost more).
Either way, ask me any questions you have, I'll be glad to answer ~
Thanks in advance.
