If you are new to the "Business Way of Life" and you have a very limited budget you may be interested in "drop shipping". This sales method will allow you to offer any product with minimum risk. I will just give you a bird's eye view of this sales method. First you should decide what products are you interested in selling like auto parts, insurance, food items...on this step sky is the limit! Then find the suppliers of the said products and talk to them in becoming a reseller. Take note that they have rules and criteria for you to become a reseller and sometimes you need to pay a certain fee to be approved.
Ok, let's say you have established your business partners and the products you will sell. Next thing to do is market these products (web, store, family, friends, prints, TV etc...), then if somebody buys any of the products you are selling, you just order from your business partners and they will do the rest (processing and shipping of products). How will you pay them? Depends really on what you and your partners agreed upon, can be on every order, per week or per month.
The secret in drop shipping is for you to make your suppliers happy and for your suppliers to make you happy. Quality of products is a must for your business to succeed, make it clean and affordably price. Hope this helps. God bless.
