File dormant LLP accounts with Companies House

I need to file overdue accounts for a UK LLP (Limited Liability Partnership) with Companies House.
Company details:

Company type: LLP (not LTD)
Company number: OC451860
Status: Fully dormant since incorporation — no income, no expenses, no transactions, no bank activity

What has already been done:
Confirmation Statement filed ✓
ARD changed via AA01 ✓
Strike-off discontinued ✓

What I need:
Prepare and file dormant LLP accounts with Companies House
All figures will be zero (nil accounts)
No HMRC filing needed — LLP, not LTD

Requirements:
Fixed price only (no hourly billing)
Delivery within 2–3 business days
Experience with LLP accounts specifically (not just LTD)
Remote work — I am based outside the UK

Please confirm in your response:
