People are always looking to have their cars washed and detailed. You could be a mobile car washer and detailer without having a permanent location. Reach out to people you know or make some flyers and put it in your neighbors' mailboxes. If you want to get serious about it, prop up a one-page website or give out business cards. You can make money quickly doing this.
They tell you that the first step in the process is to choose a niche. In my opinion, this should be pretty easy for you determine before you even decide to get started. If not, then internet marketing may not be for you. The reason I say this is due to the amount of effort required to build a profitable business from scratch. If you can’t think of one single thing that excites or interests you, then you are going to have an uphill struggle if you plan to make a go of it in affiliate marketing.
