Advice with liens in Florida - part 1

Good morning everyone. I am the treasurer of a small community in northern Florida. We have 147 lots and the developer still owns 45. Our HOA dues are only $120 p/yr. Our CCR's state the developer will turn over control when 60% of the lots are sold. This occurred toward the end of 2005. In 02/2006 at our annual meeting, he advised us control of the HOA was now ours. Our CCR's further state he would be responsible for dues on unsold lots. Now, 3 years plus later, he has provided us with only token payments and is in arrears over $30,000 including interest. We have filed liens on 15 of the most valuable lots. We also have had our attorney, 2 different ones actually, contact him to resolve the issue of us getting deeds to common areas, etc, and he has ignored all attempts to contact him. We have spent at least $4000 now trying to pursue him for dues and for deeds etc. The economy being what it is, he probably has no money. What are your thoughts on how we should proceed? I will point out that I believe we have 2 separate issues here, monetary(dues) and nonmonetary(deeds).
