UK Fixed-Price Accountant for 2 Self-Assessments & Partnership

We are seeking a UK based accountant to provide a fixed-price quote for filing UK tax returns on our behalf. This is for two individuals who are primarily self-employed, each with a small amount of PAYE employment income, and who also operate together as a self-employed partnership. All figures and calculations have already been prepared. We require review and submission of the two individual Self Assessment returns and the partnership return to HMRC. Please confirm your fixed fee, what is included, and your availability.
