Connecting two entities is another great way to make extra money by spending less energy. So can always have an agreement with some business entity to give clients on referral basis and earn a commission. I recently hired a designer for some work and I asked him if he knows someone who can PRINT the designs for me. He referred me to his friend who done the printing work. I am sure he must have got some cut for the referral and there is nothing wrong in it. Its a smart way of earning money.
