Static website problem

Hi friends, i have the following question:

I have a company selling silicone bands for marketing campaigns for many companies here in my country, there are about other 10 companies that compete with my company.

The situation is the following: As im selling a product which has very few changes in time, this means that there is not much to update on the website, i can't make any blogging or posting because there is not like a place to do so like website 2.0 blog regarding to my topic, therefore is difficult for me to build backlinks because i dont have places ti put them, so unfortunatly i dont appear at google top 10, some of my competition is in top 10, others not .......

So what to do in this type of website company situation
how to get ranked better?

I made some research and the term silicone bands in my country has good traffic, so i wish to take some of that traffic in order to make more sales...

Remember im not selling a 1 product like a pair of shoes I sell over 10,000 silicone bands to one company for a specific promotion.

Hope i make myself clear, please try to help me,sory if my english is not very well, i speak spanish.

Thanks
