Hi hiimage,
UK based PHP developer here with 7 years experience. Your requirement can be easily achieved. My previous employer actually produced software for real estate sites so I have much experience in this sector.
My bid is actually $650 but it wouldn't let me bid that low.
I am also available on MSN, Skype, Yahoo Messenger or via email the majority of the day, every day for instant communication.
Please do not hesitate to contact me if you have any questions.
Hope to hear from you soon,
Steve
