I have 3 business idea, but I want to give out only this one for free.

BOREHOLE(WATER)BUSINESS.
(1)Do you know that 70% of Nigerian population lack access to potable clean water.
(2)Do you know that you can make at least 3k or more daily by providing a portable water to the rural dweller which will cost you between 250 to 350k depending on your location

BUSINESS FACTS AND ADVANTAGES:
(1)Water is a basic need and the demand is constant as people must make use of water every day even on a worst economic environment.

(2)Each person in a rural area consumes an average of 20liters of water every day. Which means you can make 10k by providing a better water in every populated area of 1000 people everyday.

(3)You don't need to be present for the business to grow. You only need a boy you will trust who will be collecting the money on your behave to pay into your account daily.

(4)The business has little or no cost of monthly maintenance.

(5)It has little or know risk
.
CHALLENGES: from my research, the daily returns of of bore hole water business will always decrease at an average of 11% during the rainy season which you can make good money.

AVERAGE COST OF STARTING THE BUSINESS:
(1)Land/soil testing= #15,000.00

(2)Bore-hole drilling(local hand drilling)= 50meters depthx#3,000.00per meter#150,000.00

(3)Pumping machine= #30,000.00

(4)Jp water tank= #50,000.00

(5)80blocks= #12,000.00

(6)5bags of cement= #10,000.00

(7)Piping and fittings= #20,000.00

(Plumbing= #20,000.00

(9)Generator= #50,000.00

Total= #357,000.00.

This is a common but profitable and lucrative business that is hidden from many. U can research or inquire around u locality to thank me latter.

NOTE: this business is more profitable in rural settlement, eg when come to Abuja, there are many villages like, mpape, Katampe, jigakuchi, maraba, gudu, damangaza etc.

You can also make money by allowing individual house owners who can not afford to dig bore hole to connect water from ur bore hole and pay #1,500.00 monthly. So imagine allowing 30 house to connect from ur bore hole.
