Existing PHP Script Converted to WordPress Plugin

I have an existing PHP script that I own that I'd like to convert into a wordpress plugin. This application will need to make use of the wordpress members and the members will need to be logged into use this plugin. The Current script utilizes PHP and MySQL so this should be an easy conversion for a programmer that knows what they are doing. Complete Detailed instructions will be given on acceptance of project. I'm looking for someone with an eye for detail who is SERIOUS about completing the project in the realistic time frame and understands that communication is important.
