need someone to create Roman invasion of Britain scenario

[chad_rohlfsen]

I want a scenario that takes place just before the Roman invasion of Britain and goes until say 500 ad or later. I want as many tribes (if not all) in Britain, Ireland and Northern Europe as possible. Id like it to be a very large map with room for plenty of cities. Id like most of the map to be about Britain and Ireland with the northern coast of Europe until Denmark and a chunk of Norway. Id like to keep scientific advancement as realistic as possible as well. Can I get all of the tribes to be playable? One last thing Id like the Roman territory to be advanced to its location prior to invasion. Anyone care to undertake this? I'm willing to pay if so requested. Thanks!
