I have a group mostly assembled but our GM was unable to continue running the game.

We have not rolled stats yet but we have put together a concept of players:
Outcast Detective
Imperial Guard (Spec ops)
Mechanicus Chergeion 
Adeptus Admin 
last one tbd

I need a GM who is comfortable with roll20 and knows his lore. I have a few maps and tokens already made (Just 2D pictures on circles).
