Dear employer,
My name is Alfonso Moya and I am a Civil Engineer. As such, I took up to five calculus classes in college and I was a personal tutor for over two years so I am confident I am more than capable of helping you with your project.
I am availabre right now, so after I take a look to the assigment I would get on it and have it done within 5 hours.
Regards,
Alfonso Moya.
