The mechanism for the sale of finished construction companies is very simple. A regular contract of sale and sales is concluded between the current head of the company and the buyer. As a product, of course, the company itself appears and all its assets. You can do even easier and contact specialized law firms that sell ready -made firms. Professional intermediaries in the business sale market can be found by advertising on the site . True, in the latter case, you will need to make sure that the manager of the business is a real person, and not a random (dummy) player who does not orient himself in the realities of the market and only acts as a wedding general.
