The commercial/pet store raw diets can be hugely expensive.
I found this supplier of really high quality of frozen raw meats that has made feeding my 2 dogs (@ 65# each) very affordable and convenient.
The have an extensive variety of meats and are very focused on sourcing healthy(not factory farmed) meats.
Depending on where you live(they are in Indiana)- the owners make a monthly delivery route to several states!

A friend of mine gets her meat from a similar type company that is down south - I want to say the Carolinas or Georgia - but I don’t remember the name.
Good luck!
