Job Booking System Amendments

Hi, I currently have an online job booking system which requires some amendments. I think they are fairly simple changes such as adding buttons forms to send automated emails, adding fields to forms, a small payment integration needs to be added to another page but this is implemented already but on a different page so it won't have to be done all over again from scratch. There are 3 logins on the system: a dealer login that can book in jobs etc, a customer login who can book in jobs based on quotations that they have requested and an admin login which is used to view the jobs, add comments to jobs, change job status' etc etc. Please see attached word doc for a complete list of amendments required. Please only bid if you are confident in being able to complete the work. Many Thanks Paul Rowling
