Like drinking beer? Why not try making it yourself as your side business idea? With enough patience and skill you might end up brewing something that others are willing to pay to drink. Pick up an easy-to-use starter kit from Mr. Beer online, invest the time it'll take to perfect your craft, make a unique brew and start shopping it around to friends & family to see what they think of this side business idea.
With the rise of online craft marketplaces like Etsy, people with decent artisanal skills like sewing and woodworking have an always-open market to sell their products as a side business idea. If you’ve always wanted to design and make clothes by hand, then you can start turning those fashion ideas into real, hand-sewn garments and earn a little bit with this side business idea while you sleep and customers from around the world browse your Etsy & Amazon stores.
As for other tips, all I can say is “a penny saved is a penny earned”. If you are running out of ideas to make money, start saving. Some quick “low hanging fruit” tips to save some quick cash include – switch to MetroPCS or Boost for cellphone (I only pay $20/month), switch auto insurance to Insurance Panda ($25/month), and start using GasBuddy (saves me like $100/month at least. I drive a lot).
