First, start with the organic foods market. Americans spent over 59 million dollars last year on organic products. This number is expected to double in 2013. So, if you can, invest in organics!
Consider a bike store. If you invest in a bike store, chances are you will see a return within two years. Last year there were over 2.44 billion bicycling outings scheduled in our country. And, mountain bikes (racing bikes, too) are not cheap. The average cost is around six hundred dollars. You do the math! Cycling is still growing, making this activity a great investment opportunity.
My last recommendation will be in pet farewell products and services. it sounds morbid, but great products are still needed to help pet owners say their final goodbyes to their furry friends. In fact, cemeteries for pets in the U.S. brought in $52.87 billion in 2012. This does not include all the figures for memorial plaques, wind chimes, and more. If someone approaches you with this opportunities, don't laugh. This industry rakes in serious money.
So, if you have the chance to invest in any of these markets- consider it. Do your research and speak with the right attorney.
