Some things I can do well (or at least adequately) on my own paint a bedroom, mow the lawn, bake a birthday cake. Then there are times when I hire an expert to create my daughters wedding cake or photograph the ceremony. For such milestones, I do my due diligence to find the people who most meet my needs.  If youre selling your company, I suggest you do the same: first decide whether someone with experience in M&A should help with this once-in-a-lifetime event, then engage the best you can.  (Enough said.)
