Students are always looking for ways to earn extra money while studying, below are two simple ideas for businesses you could start instead of getting a job.

Painting Curbs

Painting Curbs
Curb painting of House Numbers
When you trying to find an address you have never visited before one of the worst things is not being able to find or read house numbers, so this idea involves painting the house number on the curb outside every house, just think how many potential clients you have just in your immediate area.
So this is how it could work, you go to your local hardware, building supplies or paint shop and purchase road marking white and black paint, florescent white would be the best, you then buy or make a stencil which has numbers from 0-9 (Just make that they are large enough to cover the distance between the road and pavement, size counts here).. Once you have these materials you good to go.
I would suggest you have a look at how they currently mark roads and get an idea of layout and then I would also say do a couple trial runs with friends and families house to ensure you get your technique right.
Once this is done just work out your cost per number and then add a good profit on top for your time and you set.
Good luck.

Car Washin is Childs Play

Car Washin is Childs Play
Mobile Car Wash
Car wash services have become very popular over recent years and will increase even more over time as people have less and less time available to spend an afternoon wash their car.. Give some though as to how many millions of cars are on the road… this could become an empire and you could be offering part time employment to your friends in no time.
Ok so the concept is easy, go to your local car wash or a couple in the area, watch what service they provide and how they manage to do it quickly yet professionally, take note of the equipment used and soaps. next you visit your local wholesaler and purchase all the items you need to offer your service and you are in business.
Next wash a couple cars for friends and family and make sure you know how to do a quick and professional job, once you happy work out a price list based on the prices at the car wash and you good to go.
Hint: If you have time off during the week call in at a couple of the local office parks and see if you can wash peoples cars while they are working this is a great time saver for the customer and they could easily become regular clients every week x 20 customers = BIG MONEY for you.
Good Luck with your new part time jobs.
