to close or not to close the agency - that's the question!

Hy everyone!
I have an agency (photo/video/gamedev/3D). Half of these services of it that we will not be able to support in further. If I'll delete the freelancers (there are no problems from them about it) that has been supported that services and will delete the services from the agency - my agency rating will fall down, I know that. And now I have a few questions:
1. Which way is better - to delete the services and leave the relevant ones (50% from the whole services), or build a new agency from scratch with the relevant freelancers and services? I have a current agency rating of 87%, and for about $4K of entire earnings.
2. After deleting the agency, can I use the same agency name for the new one? Yes/no/after a certain time/the same name with changes like adding "Company" or "Studio"
Maybe it's silly questions, but they are relevant to me for now.
Thanks, and have a great day!
