Business Proposal

We have a running Ship Repair and Maintenance Business. Looking to open a branch in the UK. So need a business proposal with basic financial forecasts for 3 Years. Need to submit for visa officers. Shouldn't be extremely as detailed as to show to Venture Capitals or Investors. Should have a plan, location, employees, forecast. That's all.
I want to have a top proposal with good infographics, tables, pictures where required.
