I agree that “for consideration” would likely not cover reimbursement of expenses. That language is contract language. What it means is that a person exchanges something for something else. Reimbursing expenses wouldn't fall within that category, in my view, although I'm not a contract law expert; I'm more focused on criminal law. But I do deal with another provision that uses language like that.
The other issue is the term “exploitation”, which is a very subjective term. People have different ideas of what that means, especially in contexts involving vulnerable people. So, you might want to consider that language.
