eBay Antique Trading

Help me reach my dream to being an antique dealer on eBay. I'm currently studying Business at college and have a passion in all things old. I have no form of income or savings and I hope I can reach the £100 to buy some stock and sell them on eBay. I believe the best strategy for me is to buy cheap at car boots etc. I will track everything bought and sold on a spreadsheet. Ebay and Paypal takes fees of around 15% on all items sold and I will need to be weary of postage costs. However I have good knowledge of antiques and collectables and will only commit to a puchase when I know I can make at least a small profit. In the long term I would like to do this as a part time but if I'm lucky enough to make a living at of it, there is a good chance I will choose to do it full time. This is becuase the job market is unstable in the North East of England where I live. Increasing numbers of people are getting made redundant and unable to find work. I will greatly appreciate every penny donated to the cause.
