What type of IT company are you e.g. hardware sales, software services? The MI and KPIs will vary for types of companies and may affect my quote.
Are your accounts currently up to date?
Will you require VAT returns, annual accounts, Tax Calcs etc.?
Would you consider someone who could only commit to the remote working? I am ACCA qualified and would be able to be 'on call' all day Mon - Fri, but as I am disables would not be able to visit your site.
Keep in mind that you have more chances to win a Job with Case Study as fewer Sellers will send a proposal. Moreover the Buyer has already paid a fee for it, which shows that they seriously intend to award the Job.
