If I was in your shoes I would totally do the work. If I didn't have to worry about coming up with the money to pay for therapy that would just be a load off my mind.
Although I don't know how closely you'd have to work with T to do this particular kind of work. Is it something that he kinda gives you ideas that he has for the website and then you just work on it, say at home or something?
Can this possibly get you additional work? Side jobs or something?
