Hi.,
I am an experienced PHP developer and been working as a freelancer since 2009. I do have good knowledge on OsClass and I can make modifications on your site as fast as I can. I can start right now but as it is almost night, I can only work for a couple of hours now. But after 11 hours, I can work for as many hours as you need. (I mentioned about this because you marked your project as urgent.)
I request you to kindly provide more job details like what tasks that I need to finish.
I completed more than 60 projects in freelancer.com and all are with 100% completion rate and on time with on the budget. This shows my dedication towards completing the project. Also, I do have long-term hourly projects in freelancer which I am working even today too.
Thank you very much.
