Magento Customisation.

Hi guys.
It's nice being on the other end of a job request for once!
I'm in the process of branding an online retailer and have had Magento recommended to me as the e-commerce package to us. Both my regular web guys are too busy to handle this job- as it potentially has a 6 week turnaround on it! As such, I need someone who's comfortable with Magento and able to have the site live by mid November. we'll be providing all the branding elements & just need someone clever to apply it to the site skeleton.

At this point, I just need your best price based on the time scale and some examples of previous sites you've programmed.

I look forward to hearing from you all.
