PHP expert programmer required long term

Firstly I would like to say:

I realise that if I make my hired developer feel, that he/she is in a satisfying, productive and lucrative business relationship we'll be able to work together successfully for years which is exactly what I'm looking for on PPH. My intentions are to hire a professional developer I can grow to trust and respect so I'll never need to hire any other developer for development services.

Now for the job:

I have started a crowd sourcing website (not yet live) which was built and modified for me by a company in the states a while back while I was up in Irving, Dallas staying with family on holiday.

I need my code further tweaked and some extra features added before I get the website redesigned and launched. The backend and frontend development of my site are completely finished and working. No commercial php framework was used but MVC architecture rules were followed. There is a lot I would like to change and some extra features I would like to add on.

For example:
User messaging system
Video upload
Audio upload
Tweaks to the feedback system
and some more

My aim is to give my users some more freedom and flexibility so I have gone over every feature on the website and decided what I would do/change to improve my users experience and also decided on features I could add on to my website to make it appeal to a larger audience.


Project management

We will keep track of the project using basecamp or a software similar to basecamp, maybe teambox? You can make some suggestions. I'm honestly looking for a free alternative as I'm trying to cut back on costs.

You must me proficient in:
PHP
MySQL

Have some experience in:
HTML, HTML5, XHTML
CSS, CSS3
JQUERY


and you must:

- have good communication skills.
- be a fast worker to meet tight deadlines.
- be an individual doing all the work, I prefer this.
- be available during agreed working hours.
- have GTalk/Skype for instant messaging or voice communication, don't mind which one.

My budget for this is $1000 (fee covered)

No upfront payment will be made but we will setup "tasks/to do list" on what ever project management software we end up using and set a price that will paid at the end of each milestone of the project.

Extra terms

I'm only interested in serious programmers with feedback/reviews, work they have fully completed with references for that work they can back up. It's best not to refer me to work that's not yours as that plan will most likely backfire.

Treat this like a real job in the physical world. If we are going to build a working relationship we have to value and respect each others time and keep our word. I'm the type of client who would like regular updates through out the day and enjoys answering questions to make my developers job easier. I like a developer that can keep a promise and also give me notice for when they'll be unavailable.

If you have the skills I require and agree with my terms and wish to work with me then I look forward to hearing from you.

Thanks
Antoine
