Looking for someone to do some modification work on my social / dating script!

Hi, My name Rehman from London, UK and i am looking for reliable and an honest web developer, who could help me to modify my social/dating website. Once the tasks done, then available for maintenance on a regular basis. I had a freelancer and he did a good work, but his reliability is coming into questions. Now, he just appear for week or 2 and then, disappear for months and all my required modification works are hanging. I had very bad experience with developers in past, who took my money, but never deliver the work. So, it is very hard to trust on developer since then. I am also looking for an affordable developer within my budget, if work can be done on that budget. That would be great. Please review my required task points and let me know, if you can do it honestly or not. Please don't waste my time, if your intention not to complete my work and waste my time. I will look forward to hear from you soon. Thanks. Kind regards, Rehman
