Adobe Encore DVD job

Hello, we want to create an identical 3 DVD Set in both PAL and NTSC formats. We have already created an Adobe Encore DVD menu, and authored the first DVD of the PAL set. We converted this first DVD to NTSC, the result was 'ok'. We do not have the encore project for the NTSC version. We would like someone who knows Encore, to create two more DVDs in the PAL format with the same menus, (different text for the chapter names etc). Then we also need two more DVDs in the NTSC format. I am not sure if it is best to recreate the whole project again with NTSC data, or convert the DVDs after they are done. An issue that was encountered when converting the first DVD to NTSC was that the menu items hover "hotspot" became lower than the actual item, because NTSC is fewer pixels tall, and thus the menu items did not work correctly when viewed on computers. We can show you the ISO for this to demonstrate. We have no preference over 'how' it is done but the result that we need is: TWO NEW PAL AND TWO NEW NTSC DVDs that are the highest possible quality and have menus that function properly. 1. You will receive Adobe Encore PAL project, and the photoshop menu files. 2. You will return 2 NEW PAL DVDs and 2 NEW NTSC DVD ISO files (4 ISO files Total) This project is very straightforward for someone with good experience. We will select the best candidate based on availability, price and competency. We are great to work with and good communicators. Thank you!
