To start the business, you shall definately need an indepth analysis of the industry, risks and possible mitigation strategies, Competitor analysis and other related critical information.
For each category mentioned above, a well known model shall be used - SPELT ( for Industry ), SWOT ( for Competition ) and other which shall succintly give you a bird's eye view of the Industry and what can be expected out of the same.
Personally felt that you should not look at money for this job at this stage, because a lot more capital that you put in should depend solely on this report.
