Needing a UK accountant to help with accounts

I am seeking a qualified UK accountant to support me with my accounts and prepare a letter for a refinancing application. The letter should accurately confirm that you have been engaged to assist with my accounts over the next 90 days. The work may include reviewing financial records, identifying outstanding items and advising on steps to bring my accounts up to date. Please describe your relevant experience, availability, proposed approach and fee. Any letter must reflect the agreed scope of work and be issued only where professionally appropriate.
