Personally, I can't imagine seeing two Ts- maybe if one was teaching me some specific skills... IDK, still can't- I have trouble remembering what I discussed with one T, wouldn't be able to with two.
I have one and go twice a week (plus sometimes additional session if needed), discuss everything with him.
If I were you I'd ask your T if twice a week is possible or try the group therapy (nice alternative to individual). I would discuss it with my T either way.
As was already pointed out, not sure if you "qualify" for sliding scale- but TBH Ive never understood this concept (like how Ts decide who "deserves" it?)
