Order Types Stocks

What are some good business that don’t have you stock inventory?
I am looking for a online business where it won’t cost me to much and they don’t ask for a minimum order. Also the type of business I am wanting to do needs to stock and deliver to my customers. Please give me websites or tell me of some books that would have the info I am looking for.
look toward any service based business to get you in for a low inventory investment. try to analyze your skills or take classes to offer your services to someone in exchange for a fee. you can consider anything from maintenance to computer science and beyond. there are part time and full time service jobs always available. good luck!
