Usually asking to the author is the best way in terms of cost (time-wise). However, a lot of people are no longer writing scripts for ace nor providing support for the ones they wrote. If you are looking for a free solution, this board is the right one. You can find people to do it for free here.
Even so, as I mentioned in one of my previous posts, you might not have much luck. You might want to take a look at the classified board, where people offer their services for money. You can find a few threads of people who might do the job for you (including myself). Of course, while the said board ensures that you get the script done, it also implies that you pay for it.
If you are not in a rush, you should wait a little bit and see if anyone replies to this thread posting the script you need. The fact that it comes for free does not make it worse than a paid one. After all, we have been posting in this thread continuously, effectively bumping it many times. If you are still unable to get the script for free when you start running out of time (or if you already are in a rush) you should consider the classified board. In the end the choice is up to you.
