It is completely possible to tell someone why you don't think something is a good idea and what they should do instead without being a jerk about it.
If you can't look at your situation objectively and figure out where the issues are then you don't belong in business. A lot of business is making decisions on imperfect information. You aren't going to have internet strangers to feed you the right answers. And once you bring employees into the mix, you have *much* more responsibility and your decisions can affect those who are depending on you for their livelihood.
After two years in "business" you don't know your market well enough to price a contract. You don't possess the basic equipment to complete the work you are obligating your company to perform. You are clueless about the labor laws and insurance requirements of your state. And the concept of liability apparently escapes you. Excuse me for thinking that you are a blight on our industry.
If you can't handle some unfettered criticism from an internet stranger, you are in for a rough time being in business and dealing with the public.
