Can anyone update one of the engines as a paid gig?

I posted this in Trade section but it seems that it's cut out from main feed. Afraid no-one will see it there. So: 

One of the SER engines that I use seems to have changed and SER is not doing a good job with it. Though I see others successfully posting there. I looked into its code and urls are wrong, so probably engine developers are fighting to keep posters away. Can anyone update it for me as a paid service? I could do it myself but don't have any time.
