Business Plan Financial Model

Hi, I am looking for someone to write the financial model for a business plan we are putting together. The person needs to have experience and be able to write a detailed analysis including Summary, Projections, Assumptions, Revenue Model, Sales, Cost Of Sales, Overheads, Creditors, Salaries and VAT.

We have previously had a financial model written but it is out of date and on a slightly different model so not sure if it can be amended or not. It is available to see exactly what we're looking for though.

We could also do with some guidance on business plans and any help where that is concerned would be helpful. This is to go out for a large amount of funding so needs to be professional.
