Moving from excel to quickbooks - margin scheme

Looking for a UK based accountant who is also familiar with quickbooks online.

We currently have our stock on the margin scheme and would like an effective way to have our products on quickbooks, to automate the necessary data entry required for margin scheme and for the necessary calculations to be carried out, and data to be stored and organised in a way needed for HMRC for margin scheme.

An accountant with good knowledge of the operations of quickbooks would be great. Ideally someone London based who could come to work with us here in Islington Angel on an hourly basis (we are very flexible for time and days).
