Custom perl modifications to a script

Hey, I need people that worked with XFS only, If you don't what it means - this bid isn't for you. I want to make some modifications, Not many, but some that will require a few hours of work. Please contact me only of you worked with this script in the past, I will provide the exact list of tasks needed. Please bid based on 5 hours of professional work. I don't think it will take that long, but we will discuss that in messages. Please send 1 link of site you worked on in the past, so I know we are talking about the same script. Thanks!
