CPA for Property Sale Dissolution

My co-owner and I are finalizing the sale of our C corporation’s sole asset—a small commercial property in New York—for under under $350 k. Ownership is split 85 % / 15 %. All prior federal and state filings for the corporation are current, and once the sale closes we intend to dissolve the entity for good.

I need end-to-end accounting support that covers:
• Recording the sale and allocating proceeds, including basis adjustments and closing costs
• Computing the corporation’s capital gain and any associated federal or state taxes
• Mapping the after-tax distribution to each shareholder and explaining any dividend or return-of-capital treatment
• Preparing and filing the corporation’s final federal and state income tax returns, plus dissolution paperwork with the relevant Secretary of State and tax authorities
• Delivering shareholder-level schedules so each of us can report our personal tax results accurately

Access to prior returns, organizational documents, and the draft closing statement will be provided. A CPA experienced with small C corporation liquidations, multi-state property transactions, and Form 966/Form 1120 final returns will be the best fit. A closing date has not been established yet. As long as closing does not get further delayed in this tax year, completion shortly after closing would be desired so we can wrap up the entity before year-end, but is not critical

Please outline your approach, anticipated turnaround time once documents are in hand, and any state-specific steps we should expect.
