Customise OS Ticket

We are looking for a php coder who can modify a copy of the latest version of osTicket (currently 1.6.0) to include two additional (optional) fields, and modify the 'view ticket' screen to display a click-able link, if one of the additional fields is not NULL, containing a part-static, part dynamic address. i.e. if Additional Field 1 is not empty, a text link on the 'view ticket' screen should show that points to [login to view URL] With the xxxx value being retrieve from the contents of Additional Field 1. The same applies for Field 2. The winning bidder will also be required to create a Codeigniter 2.0.0 library class called [login to view URL], which can take the contents of a web form and interface with osTicket to create a new support ticket (including getting osTicket to generate its standard emails). The class should also have functions for the following:- * To return the number of currently open tickets * To return the number of open tickets assigned to a specific person or department If you have any questions or queries, please do not hesitate to contact us with a pm and we will endeavor to answer the query as quickly and in-depth as possible. We have a requirement to use osTicket, so any suggestions on using alternative software is not required. The amount of overall work required in this project is not believed to be excessive, and we are looking for bids that are towards the lower to mid-end of the stated range.
