Trying to aquire Reo Listings

I'm Trying To Develop Some Contacts With Banks, Mortgage Companies, & Asset Services Companies.
So That I Can Acquire Reo Properties To List, For Instance, Reotrans, Ocwen, Bank Of America, Pas,Reo, Precision Asset Management And Homeq Reo.  
In My Search I Found That Some Will Let You Join For Nothing. Others You May Ask You To Pay, From $59 To $995 A Year, I Wanted To Join One And Thought I  Would Run It By The Realtors In The Group Hoping  They May Be Able To Tell Me Which One Was The Most Productive One To Join. I Tied To Join Pasreo , I Think It Was About $995 Year, But  You Have To Be Invited Also. I've Worked With Homeq With Shorts Sale(No More Of Them) And I Listed Hud Homes For A While, But They Cut Me Off And Made It Clear They Had All The Realtors They Needed. Ocwen Is Ok But They Take 1.5% Off The Top Of The Sell Back. I've Been A Realtor For 8 Years And Have A Crew For Trashout And Repairs But Realtors Are Reluctant To Help You Break Into This Area Of Real Estate.
