I'm 17 (going onto 18) and I want to set up my own shop once I've left school. I had an idea of owning a shop similar to Cex where people trade games etc. for money, I then sell these games in my shop and online for more money than I bought them for. I would also sell a few computer items such as HDD's and graPHICS CARDS ETC. Is this a profitable business and would I see results within the first year? Thanks for reading.
