yup... double blade .. on the straits times newspaper ... almost every day there will be piano classifieds. People who have done this for ages buy/sell/trade pianos.
If you want to earn even a small margin. The customer wont choose you because if anything were to happen you are simply too young to be held fully responsible. He will have to look for your Daddy...
Say the guy sells the piano to a buyer you sourced. and the cheque bounces , if he cant find the buyer. You will be held responsible , but who is responsible for you?
Did you think about the increase in your transport?? to meet "clients" will your time schedule allow? having school and all? ...you wanna do it in your free time? if you wanna earn money in free time , do some MLM or take up a part time job.
Will your earnings pay off simple stuff like increased handphone bills due to discussing with clients. How many of your friends/family members own pianos and wanna sell them? If they wanted to sell they "would" probably entrust you to do it for a tiny commission fee. But how many pianos do they have? how much family do you have?
HAHA have you thought that if both seller and buyer get a chance to communicate. You will be cut out of the loop in an instant. How you going to arrange transport?... hire movers? Trust me no one will let you move their 3.5k item to an unknown location with no money up front. And nobody will pay money upfront for a piano they cant see and play.
If you can keep both sides blind. You will have to function more like a trader... buy first. then sell for profit. But you have no startup capital , no storage space , no experience.
Anyway this kinda things you gotta think bigger. how much you are planning to earn by just being the middle man? If you let your customers quote the price they WILL quote high. If you ask them to reduce their price. they would much rather just post on classifieds for 50-60bucks to a wayy wayy bigger pool of potential buyers., unless you can promise something like a sale in a certain time frame. But do you have the customer base , skills , knowledge of product , time to take on such responsibility??
Its good to have interest in learning to make some money on your own. But you have to do it sensibly. Something that i feel only comes with age. im 23 and im still getting there.
