For promotions to be added there are several I'd like to see, but here's one I found recently that I'm liking and has the underground feel I think is missing in EWR.
Anarchy Championship Wrestling (Texas) http://anarchychampionshipwrestling.com/
Roster is here, 21 of them are in game now (Rachel Summerlyn is too, but she recently left the promotion) http://anarchy-roster.blogspot.com/
While technically not a backyard, they're not much bigger than that. From what I can tell a lot of their shows seem to take place in a bar. I'd say 100k max for the budget, risk level in the mid to upper 80s as they are a hardcore promotion, merch is limited to just DVDs so I don't know how you'd rank that, their advertising seems to be done through social media mostly so I'd say 1-3% max.
Darin Childs and Jacob Ladder are the founders so they need to be unsackable.
Events: I tried to put them in the right months, but the order seems to change year to year. This is 2012's though.
January - Guilty By Association (their biggest event)
February - The Gateway to DANarchy (think this was a one time event)
March - An Absence of Law
April - Peace, Love, and Anarchy
May - Nothing is as Real as a Dream: A Pro Wrestling Prom
June - American Joshi Queen of Queens Tournament
July - From Innocence to Insanity
August - Distrust, Dismay & Anti-Social Behavior
September - The Evolution of the Revolution
October - Beyond Good and Evil
November - The Annual Lone Star Classic (Tournament)
December - Delusions of our Childish Days
