Customise our vTiger CRM

We have a new installation of vTiger hosted on our servers. Our company offer online qualifications. In addition to using the CRM in the conventional way (ie - as a Sales tool for generating leads, converting leads to sales, invoicing etc) we would also like to use the same system to keep detailed records of the student's progress throughout the duration of their qualification(s). We would like to customise our vTiger CRM so we can record the following data against a customer: -The qualification(s) they have chosen to do (please note that the same customer/student may choose to do multiple qualifications) -The unique details of each specific chosen qualification (such as their registration number, their allocated teacher, the units of the qualification they have chosen, their target completion date, their actual completion date, etc) If possible we would like the customer (student) summary screen to show the qualification(s) that the student has paid for (both completed qualification and 'live' qualifications) and clicking on each of the qualification links takes you to a screen where you can see detailed information specific to that qualification. I have made 2 quick knock-ups of roughly what we are hoping to achieve. If anyone has the skills and/or is familiar with vTiger (SugarCRM) please get in contact with a quote for the development of our CRM system.
