I have been working on these maneuvers for six months once or
twice a week (weather) here in the North East and am still not ready
for the check ride. How many hours will it take??

Once per week really isn't enough, in my opinion. Twice is marginal.

Then the question arises, do you want to be good or just pass a
checkride?

If the latter, then 20 hours should get you done, though a lot depends
on what airplane you're flying and what airplane most of your time is
in.
