Designers are encouraged to use their creativity, the website will be designed around this new logo so I don't really want to place too many restictions on what people are able to come up with. However, my preferred placing for any logo is the top left of a banner header, it could anywhere in the banner and even take up a lot of it I suppose, but I'm planning on having the shopping cart and a search box at least in the header banner so room would need to be left for that.
The logo should contain Big Mens Large Clothes (with or without the .co.uk - whatever you think looks better). I'm not all that keen on the name 'Big Mens Large Clothes' - I think it sounds a bit weird - but rather than change domain name we've decided to embrace it so extra points go to those who find a way to make it sound a little less stupid!
Also the logo should be serious and manly.
Basically thats it - I'll give plenty of feedback for those who take the time to enter.
