I like having multiple products & services within industries. This allos for the highest ROI & is easier from a SEO standpoint.
If I were promoting your company I would do the following:
1. Hire a content copywriter to write a seperate page on every service you sell. You broke down your services great on your auto insurance page, now you need a page on each one.
2. Add breadcrumbs to your site. Search engines index web pages not websites so adding breadcrumbs really means extra links everytime you add a page. Plus it tells search engines which pages are more imprtant then others. Your breadcrumsb should be:
Main Keyword > Section > Category > Page
Fash Gate Services > Connecticut Automobile Insurance > Collosion Insurance
3. Choose a few of your most popular services
4. Start massive research. I want to find every related company, website, event, and organization that relat to these services. Once you find them figure out a plan to partner, advertise, buy links, or anything to build brand awarenes or links within the industry.
But I do agree that computer services & tax preperation don`t really make sense on this site. Maybe your company has a great business model for this but to me it would make me question the reputable status of this service company.
