Hi!
I'm interested on this project, I have seen your website and I realized that it has so many opportunity areas so I would like to enumerate some improvements that can be done:
1.- Use more contrast in your website
Blue over white is not a good option as the end user could be dazzled after 10 minutes and leave.
2.- A picture is worth a thousand words
Try to use more pictures or graphics on your website to make it more pleasant to the view.
3.- Use a column layout
Organize the large amount of data displayed in columns.
I would create/use a template matching dark grey and blue (I guess that's your corporate color) and I would use PHP, MySQL and HTML/CSS to rebuild a completely new website.
Social networks would have a great impact on your visits/sales if they are correctly implemented.
Now, the project I described above would cost more than USD $500 but I'm new on this page and I want to prove my knowledge, so please check my bid and let me know if you are interested.
Please note that I wouldn't use any CMS for this, pure PHP/HTML, CMS tend to create more workload when used. On the other hand, I would create a little backend for you to be able to update your products/services so you don't need to be a programmer to manage your site.
If you are interested, please dropme a message at darkzoft (google mail) so we can address further details.
Kind Regards!
