I need someone to redesign an existing logo

I have a logo for the website www.businessweaver.co.uk, but it does not work for the intended audience. The website is now going to be aimed at larger businesses, so I need a more business-like, non-cartoon version.

There are actually 2 logos - a standalone small one and an extended one with the spider sitting ina web - this is used in the top left of a webpage and extends horizontally along the top margin and vertically down the left margin.

Keep to the same colours (same 2 shades of blue, plus black and white) and the same theme - spider in web, but it needs to be for a more grown-up audience.

I need a fairly quick turnaround - 5 ideas, revisions if necessary on a couple and then 1 chosen, and then creation of the (2) final logos in photoshop psd format all within 3 days maximum.

Can you help? I'll need to see examples of other logos you have doene for enterprise-sized companies.
