Loan Service Companies?

[Arthur Lyons]

I recently read a book about raising private money by Susan Lassiter called getting the money.  In the book she talks about the importance of finding a loan servicer to handle the money doing transactions from your private money lenders.  I am having a hard time finding such company.  A company that would hold the funds, disperse interest payments, record a lien until paid, and allow the lender to tract the progress of their investment over a period of time.  This gives the private money lender a sense of security and transparency and keeps funds out of my bank accounts. Does anyone know any companies that do this well?
