The company I work for has never spent much on advertising because after 20+ years in business we get a lot of referrals and upgrades.

We updated the website anyway. We also decided to try and shift back to mostly local work so we did a big marketing campaign. Those two things together seem to be working. People are calling us now because googling manufacturers names brought us up on the first page of hits.

I think you will be pleasantly surprised once your new site is up.
