To be clear, I don't believe what you are suggesting is illegal in any way, but consider this --
Suppose you hired a guy, he worked for you for a lot of years, he built personal relationships with most/all of your clients. At some point he decided to start his own company competing company and continued to work for you while he was getting it off the ground. After he quit, he called all of your clients (Owners are clients just the same as guests) and told them he was leaving to start his own competing company.
Would you be angry? If it impacted your business would you consider suing him to prevent it?
You don't have to break the law for someone to sue you and losing in court is not the only way to lose a lawsuit. In fact, you could prevail in a lawsuit and still lose. Contacting your current employer's list of owners regarding your new company is a very dangerous game -- if your current employer finds out about/suspects it and is in any way litigious, you could be headed for a lawsuit that you may likely lose.
Even if all you do is contact owners and let them know you are leaving, and don't even tell them where you are going, a lawyer will paint it as if you paid them money to abandon your former employer in favor of your new company.
So ask yourself this question;
If you shared everything you've said in this thread regarding your intentions with you current employer (probably leaving out the comments about her kids), do you think she would be OK with you calling the owners who list with her to tell them that you are starting your own company?
If your answer to that question is 'No', then you should be very careful.
If there is another directory of owners that you can use that does not belong to your current employer that hopefully includes owners you know and those you don't purchasing/renting/leasing that list, then calling owners you know from that list would be a much wiser way to go. When you call them, don't mention anything about your previous employer. When they ask you, you should have nothing but praise for her and her company and best wishes for her success. Do not draw comparisons between your two companies -- focus on what you do and why you are the best. Don't let anyone bait you into saying anything negative. When asked about my fiercest and most hated competitors, I always respond with "They do a great job and I wish them all the success in the world." If asked again, I respond the same way. Eventually people will stop asking about my competitors and focus on what I'm doing. Don't give anyone anything that they can take back to your previous employer and get you in trouble with.
Good luck man -- and be sure to let those of us on the .Org know what your new company is so we can use you if we're looking for rental cabins in your neck of the woods (unless that constitutes advertising that is not allowed on the .Org without proper compensation
).
