Help! Need patient referrals........

Hello

We are new a home care agency (we just got certified by CHAP in Jan 2009). The competition is extreme in the city we are located in. There is one BIG home health agency "the big guy" (our competitor) which has been in this community for almost 25-30 years. All the physicians and hospital discharge planners are sending the patients to the our competitor- "the big guy".
We have been working very hard with marketing, visiting the hospital, discharge planners etc....yet our patient volume is VERY low. If this keeps up, we would have to end up closing the business! We need ideas to increase patient referrals....we are pretty DESPERATE right now . Any ideas/comments is appreciated.

Thank you
"new hha".
