UK Tax Reporting service outsourcing

We are a firm of accountants and tax advisers servicing the medical profession in England, Wales and Scotland. Our clients are, in the main, NHS Consultants with private practice. Many operate as Ltd Companies, some as sole traders and some have property companies as well. Due to circumstance, we find ourselves under pressure this year and are looking for another firm to prepare accounts, personal and corporate tax return for my colleague to review and submit. Currently he is using IRIS software. Whoever we engage needs to be able to prepare Satutory Accounts from bank statements and informal notes. We are looking to engage with someone asap.
