PHP/Air Platform Custom Desktop Software With SQL Licensing Needed

I need a desktop application with licensing system built to the spec below on my platform that I own. Coding is preferred in Adobe Air, but PHP would suffice. If you prove worthy, I will use you for multiple projects in the future. You MUST be able to prove your competency for this. It will be 100% my coding at the end of the job (you cannot resell the coding that has been done for me and I will of course require the source code) and it needs the following features: GUI Design Multi-threading Proxy Scraper (I can provide the source of where to extract) Progress Log SQL back-end Licensing Script System to enable and disable licenses Debugging tested and seamless functionality Song & Video play increasing Increasing profile views Delay feature for all features - i.e. so it carries out each process between for example 3 and 12 seconds. Adobe Air preferred but php is fine You must have a track record of good development work and regarding payment, as soon as I see a bare working version of the program, I will release half the funds... once complete and we are happy, all remaining funds will be released ... I am looking for a long term partnership so if you are good, I WILL use you again. I always pay and always on time... Se my feedback. I need you to also be available to start work shortly for this... Message for more information - I can provide an example of this..
