improve and detail the business plan for a mobile app startup

I need to reform a business plan. The content for the plan is already developed there is some content editing required plus there needs to be validation of the data used. The contents for the plan are: 1. Executive Summary 1 1.1 Highlights 1 1.2 Objectives 1 1.3 Mission Statement 2 1.4 Keys to Success 2 2. Business Description 2 2.1 Company Ownership/Legal Entity 2 2.2 Services 3 2.3 Management 5 2.4 Financial Management 5 2.5 Start-Up Summary 5 3. Marketing 6 3.1 Marketing Analysis 6 3.2 Market Segmentation 7 3.3 Marketing Strategy 15 3.4 Competition 19 3.5 Sales Strategy 27 3.6 Pricing 28 4. Financials 29 4.1 Financial Plan 29 4.2 Company Valuation 29 4.3 Start-Up Expenses 30 4.4 Determining Start-Up Capital 32 4.5 Cash Flow and Profit & Loss Statement 36 4.6 Margins 37 4.7 Break-Even Analysis 39 4.8 Balance Sheet 40 4.9 Sales Forecast 40 4.10 Milestones 45 4.11 Balance Sheet 47 4.12 Important Assumptions 47 4.13 Appendix 47 Most of the parts are fully developed, however some research will be required for the data to be used. The formulas for Sales forecast, market reach and income flow have been derived on assumptions using the business model. However some research will be required in these sections as well in order to validate the formulas used. For the marketing strategy, the content needs to be written and major research has to be done for the market demand specifically. The data needs to be for the years 2017-2018. The freelancer needs to have a statista account or any such platform which offer valid paid data.
