Logo for ebay store/ business card

I'm looking to get a logo for our new ebay shop "LJ UK Distribution" as yet I've not really any ideas of a logo colours etc I'm thinking bright and funky with a professional edge. I'd like some sort of sign that you associate with the company e.g apple for Apple, the M for McDonalds etc. we will be selling anything from phone chargers, ecigs to sinks. So it's quite a wide variety of products. I'd like the logo so I can use it on the shop and over the item pictures. If you need any more information please contact me. Thank you
