Modification & Customisation to php script

Modify HESK php ticketing system to put customer information into our customer table (name and email) and refur in the hesk table to customer id. You will need to download hesk, create a sample on your own server of the software and modify all features accordingly. You will be given our schema of our database but will not have access to the database its self. You will also need to create a script to tranfer all the existing data (name and email) from the default hesk system to our customer table. You will also be required to add our old ticketing system table (very simple table) into our hesk table. Please download the hesk software and review before bidding.
