Write some Software

I am looking for someone who can create a decision tree style website where my property tenants can report their maintenance issues using a flowchart style of questioning. For example they select the type of problem they have and then it narrows it down to further sub issues and so on, they need to be able to upload photos of the issue they are reporting and also provide their personal details (name, address and contact number). The report then needs to be emailed to admin and also be date and time stamped. I would like it on a subdomain of our existing site i.e maintenance.([login to view URL]) which is built in joomla but failing that it can be built entirely on a new domain which I'll provide and we can just link to it. I have an exact example of a website that I can provide where the design layout and functionality etc can be demonstrated to make it simpler for you to understand my requirements. Thanks
