Website design and building

Over the past few months I have been working on a few new companies and their websites:
My design site - www.offaxisideas.com - this shows all my latest products and future designs
Secret Santa Presents - www.secretsantapresents.com - this is an online shop selling fun novelty products
Secret Santa - www.secretsantapresents.info a blog and site about all the latest great products and Xmas gifts
Freeze Frame - www.freeze-frame.eu - a camera hire company based in the alps, hiring, filming and editing footage for holiday makers.

Check them out and see what you think.
Some of the sites have taken a lot of time, the others I quickly designed. The SEO and back linking seems to be one of the hardest parts.
If you have any thoughts on any of the sites I would love to hear them.
