Hi,
I have read the project description and I see that you want to hire a developer to decode the gzipped plugin and fix issues with it.
If you can send me the files, I can take a look at it and see if its easily editable.
I have done extensive work using PHP, MySQL, Wordpress, Ajax, HTML, CSS etc during this period and I can handle any platform with full command.
Please let me know if you have any queries regarding my proposal and I will be happy to answer them.
Thanks
Satinder Rana
