Hi,
I like this job very much, because I am good at it and like to use it.
I understand you are a student, so I just charge $10, but the extra fee is $5, so total $15. I don't figure out why the extra fee is so much.
Anyway, if you choose me, the price can be negotiated.
By the way, I am a freelancer with much time, so I have enough time to teach you. Sure,you can ask me questions anytime.
Looking forward to your offer.
