Help with Crusades Mod

[PoetclyPathetic]

I have been working on a Crusades mod/scenerio and would love some help with it. I am almost done with the map, but cant figure out how to pick which civs are in it and rename them to Jeruselem, Franks, Muslims, Holy Roman Church, Byzantines, id like one more civ on the side of the muslims ;limit tech at medievil era only; change attributes and rename units; and set hold point as victory condition like you could do in civ III . Would anyone care to work with me on this mod?
