I will be openning a mobile phone shop ( retail outlet )and accessories shop in Kolkatta. I plan to keep 5 pieces of all the popular models of Nokia , Sony Ericsson , Motorola etc . So should I approach the mobile phone dealers or do I approach the marketing offices of the respective companies for getting the stock in my shop ?

Thanks for your time.
Any additional help or tips will be appreaciated.
