Check out the classifed section. I saw a few people in there last week that were reasonable priced.

Also, they have a lot of free templates you can mess around with in the wordpress blogs that look ok if you're just starting out. Something just to tinker with and learn the ropes

Could you expand on what you mean by "what sort of blog" you need - do you mean what software to use, or the structure of the text withing it?

hi,
I mean the actual design.Do i go for a product review site or a blog on the subject and then sub domains on other keywords in the same niche.

It depends on what you need. There are review sites using wordpress and I use my own version which is dedicated and fit for Internet marketers. I also use different wordpress themes for different kind of product but still it depends on your taste.
