I too have just started up in business (in Ruislip). My DH designed my website (www.scribe-services.co.uk). I am not quite as far along as you are.
I really liked your pictures and the pages seem really user friendly. The photos are great. The only thing I would suggest is maybe changing the page background (table cover check). The whole look of your site is quite upmarket and while the backdrop matches the colours on your front page, it does not match the sophistication of the rest of your offer.
I've recently started a new catering business specialising in hone cooked party food and celebration cakes. I think Toni (my web designer/ friend) has done a great job but really interested in your feedback on the site and my products.
