I've been building websites for the past 10 years. I have 2 developers working for me as well so between us we can usually tackle most web projects.
A basic CMS website would be in the region of £800. Something a bit more bespoke (with advanced functionality) will cost between £1,000-£3,000
I'd always be happy to send you a quote for any web web you might be offered. I'd also be happy to put your company website / copyright within the code so your client still thinks you've created the site.
Here's a link to my website: Web Design Kent | Graphic Design Kent | Design studio in Tunbridge Wells
(I'll be adding a few new websites we've just completed in the next week or so)
