Abbreviated company accounts for very small business

General information for the business: Need balance sheet for HMRC for small limited company - abbreviated accounts only balance sheet. Being able to work without the activation code for HMRC gateway would be an advantage in case it doesn't arrive in time.
Industry: Healthcare
Kind of support: Basic accounts for HMRC for limited company
Description of support work: Small limited company with one employee - needs main figures extracting for HMRC online system for Corporation Tax. All account entries are listed and organised on a Barclays accounting system so main figures just need extracting. There isn't much to do as the business is almost dormant. The deadline is Thursday evening.
Extra notes:
I don't yet have my Gateway activation code - it will be arriving in the post tomorrow morning (Weds) so I will have it then. The job is for HMRC accounts only - not for Companies House accounts in this instance.

Summary of situation:

This is the first year of accounts for this business.
Already registered for Corporation Tax with HMRC
Not activated the account yet - activation code arriving on Weds 29th April

I have not submitted accounts to Companies House yet (yes, I am behind with this but the accounting period is different) and this is not required in this instance but I will require this soon.
