Putting up a business

I really wanted to have my own business but it's difficult to decide what kind of business I'm going to put up and also that fits my budget.My friend's husband who is also looking for some business opportunities,told me that maybe they gonna invest on franchise opportunity.He said that there are many other franchises to choose from,like health and fitness,business services,pets,cleaning services,retail franchises and many more but they will choose a franchise that is related to food.Lucky for them,they already have a sufficient capital to start their business.
