Clearbooks expert

Hi I am looking for an expert who can use our current accounting system Clearbooks to process our backlog of payroll for 1 employee to bring accounts up to date with HMRC. I will process monthly payroll myself once everything is updated. Maximum period of input is around 6 months. Previous accountant had submitted part of the payroll but not all has been submitted and need to bring accounts up to date to satisfy outstanding tax bill. I do not want to use an external payroll system it needs to be our own system.
