Adhoc work and changes to standard

I need a programmer who can assist me on my adult website www.sexus.dk. The software behind it is from Skadate and I will only consider programmers with knowledge of this script. The task is Adhoc - meaning from time to time I need assistance in solving issues or making changes to the site. I am looking for a long term relationship. I'll pay on an hourly basis or upon agreement on the issues showing up.
