When I upgrade my TH to 9, my condition was more or less like you with one difference. Honestly I've got a 4th builder today only. Now, since you got 5 builders right of the bat, your condition can be improved faster.
Should warn you though, it won't be easy and requires patience. Just remember, you're not the only one with this condition and premmie base comes from every TH level. Thus you can still raid other premmie base too!
