Executive summary for business plan

We have a business plan which is 99% completed which we need an executive summary for - we know the exec summary is the one bit everyone reads (and sometimes the only bit!) and we want to ensure that what we present hits the spot so we would like someone who has experience of this to write it for us.

The business is a B2B SaaS business and the immediate requirement is for an executive summary for bank/finance company use - we also will need executive summary for investors but that is not the immediate requirement.

You must have a business or finance background and have experience of business plans and executive summaries ideally in the UK/US markets and be able to provide samples of previous work and client references as the data in our plan is highly confidential and we will not share it with anyone who we do not 100% trust.

Thanks
