It could be that your target market (people in debt) is one in which people have a lower ability (or willingness) to spend. (Google Ramit Sethi's Pay Certainty test.)
In that case, perhaps an alternate revenue system can be found. Maybe something like Mint.com.
I read (listened) to Chris Anderson's book Free: The Future of a Radical Price [1], which tackles this very subject of creating revenue from free products. (Chris Anderson is the founder of Wired.com and this book debuted as #12 on the New York Times Best Seller List.) You may find his book useful too. I highly recommend it. Best of all, the book is priced appropriately: Free.
