I'm going to assume you understand that you should write a business plan for the business idea you select, and that the true obstacle you are having with any of these three (3) businesses is that you cannot acquire adequate marketing data to support your assumptions.
There are two (2) types of marketing data, primary and secondary marketing data. Secondary marketing data is the type you find from census.gov or any other online resources. Primary marketing data is data that is collected directly from a potential consumer.
To obtain Primary Marketing data this is what you need to do:
1) Define your target market
2) Develop a simple (no more than 10-question) survey using 1-5 rankings involving key factors of the success of your business
3) Implement the survey - Yes, go out on the street corner (as BusinessWithSuccess suggested) and ask pedestrians walking in the area of each of your desired locations.
