Yes, I can do level scripts. They're really not as hard as everyone bigs them up to be.
If possible, could you try to get the mapping done or at least partially finished before I start? It will be crucial for the execution of the script. That and, seeing how it is a two part script in a way, I'll need to know the map bank and number of the place through the hole, otherwise I can't link the two halves.
Other than that, I think I'm all good. Though I was wondering if I could possibly go through and correct some scripting errors once I get some free time. There are a few minor things here and there that could be improved upon (such as "preventing" a script tile from executing a second time by using flags, as opposed to variables). I don't know who has scripted for you thus far but I hope it would be okay it I tweaked a few things in a couple places.
