As always, I would suggest not to concentrate more on the META data content.
Once you have a one line information about your company and services with your major product names or keywords, you can add it to your title or description tag of your homepage.
Some add keywords to the title and company information to their description. I would say, even this would do better. Always give information for the visitor or searcher and get their interest, they would automatically click on your link once they are interested.
Make sure you have the best words visible on your META in the Search engine listing. Other than this, you dont have to worry much on META data.
