I agree with GT. First thing you are better off running a business alone. When money gets involved you don't want to deal with anyone esp. someone from internet. I would highly suggest you to not even  involve your friends or relatives since $ ruins a lot of good relationships. Also partnership business is very risky, they can take a huge amount of loan and you will also be held liable.  

If opening business alone is not possible at this time, you should look for someone who you can trust and know for a while or wait until you save more money. 

good luck
