Hello, it will be a great pleasure working with you on this project. I understand his budget limitation, I already had clients who started paying me little and, after his business grew, this client hired me to implement changes on his website, so I will charge a little below.
I will certainly finish this project quickly, efficiently and, above all, completely satisfactorily!
I have set a deadline of 4 days to deliver the project, however, this is a deadline, already covering any and all complications, I am sure to complete in an absolutely shorter time.
