Looking for a solicitor to write a letter to CPS

Hi, I am looking for a criminal solicitor to write a letter to CPS to withdraw a serious report I had made (the issue has been resolved, hence why I will be withdrawing my police complaint.

The case is with the CPS and they require a letter explaining why I’m withdrawing, but I would prefer if it was written by a solicitor.

I can explain the situation in detail to the suitable candidate.
