How to improve my conversion rate ?

[Alfredito]

Hi,

my websites are getting very nice traffic, more then 80% are new visitors, but my conversion rate is not so good as before , i guess it went down due to the economics problems.

I saw a few companies online that offer these kind of services - to improve conversion rate, but of course they are not cheap and i would hate to spend $2,000-3,000 on a company that wont bring results, they all know how to sell themselves, but are they for real ?

So my question to you guys is if you know a company that will redesign my website and get me better conversion rate. Or if you have other ideas how to convert more.

My sites are in my links.

Thanks a lot.
