Does your professional ethics allow you to recommend the services of colleagues from other cities? I'm not from Boston but would like top-notch service. It seems to me that if one company can advise another company of the same profile of activity, this is the best advertisement. It's even better when you have branches all over the country, but here it's up to someone who is lucky. For example, at my last place of residence, I used the drain cleaning service Anaheim. I was advised by my boss, who had built his house himself, and made acquaintances with all the companies that would help him "revive" the house.
