Customize OSTicket v1.9.0 - Custom Form

I need someone who is familiar with OSTicket v1.9.0. Candidate should have prior experience customizing the form that creates a new ticket. The default form asks for simple information like Name, Email, Phone Number, Issue Summary and Issue Details. I need something much more involved. I need the form to request: Name, company name, street address, city, state, phone, email. Then I need it to also have drop down lists as well as other required information such as a list of operating systems, the model of hard drive used, the serial number of the hard drive, etc. etc. This information would then need to be displayed within the ticket itself. This will be a highly customized form, and it must work flawlessly within OSTicket. Please be ready to show examples of previous work you've done with regard to OSTicket.
