Create XRBL calculations for our already completed CT600/accounts for two tax periods and submit to HMRC

I asked a previous accountant to create our CT600s and company accounts for two tax periods, and then to do the XRBL calculations and submit everything to HMRC. The accountant did the first part - creating the CT600s and company accounts, and then supplied them to us in PDFs. However, he then said I should send those to HMRC on paper, which, as you know, is not allowed. I therefore am looking for an accountant to take the PDFs created by the other accountant to: 1. Do the XRBL calculations. 2. Submit the entire tax return - the CT600s, the accounts and the XRBL part to HMRC. I do not need the accounts sent to Companies House.
