How is this problem solved? -

Problem:Joe has $4000 to start a business. He does not know what type of business he wants to start, but he knows the following:-He is willing to invest all of the $4000 to start the business-He lives in a very large city, with potentially millions of customers-He expects an average monthly profit of $400-Sales or service are two main options for the business-Joe is willing to work 24 hours a dayWhat businesses could Joe start that would meet the above stated requirements?

Dear, if Joe has $4000 to start the business, I think it is more easy for him to do some import from other countries especially from developing countries. As for as I know, if you do some import, you just have to firstly pay about 30% deposit. Then, if he lives in a large city, as you said there are potentially millions of customers, he can firstly find some customers and then decide how many products he should import.For the coming of Christmas, our fireplace export very well.If there are something I can do for you in the future, please feel free to contact me.jessica851230@yahoo.com or lfx.jessica@gmail.comGood Luck to you~~~
