I cannot say which of these guilds would be open to recruiting, but here is the main guilds for each faction.
CoM - RUOH, AZN!
TB - CIA!, ESF
SL - NmE, B^L, FWAP (forgot to list them)
Minax - TACT, F!U
I don't think any one group sticks to a certain template, they all seem diverse. Each has something unique to offer though, you'll have to watch them in action to find out.
