Can an adoption lawyer help with an adoption subsidy?

My spouse and I have had two foster sons for almost 2 years now. They both have ADHD and some other emotional problems. They are on medication and also get regular counseling. Department of Social Services is pushing us to adopt and we want to but we are afraid of not being able to afford their medical costs after the adoption is finalized. The Social Worker assigned to our case from Baltimore DSS has said we may qualify for an ‘adoption subsidy,’ but she says she can’t give us legal advice and we should talk over the financial ramifications with a lawyer. Are there lawyers who specialize in this kind of work and how do we find a reputable one?
