Here is what I've got:
Hello (name),
After two wonderful years with (Salon X) I've decided to move on in my career. I will miss everyone at (Salon X), and I am thankful for the opportunity they gave me X years ago. I am fulfilling a dream of mine and opening my own salon. The name of my salon is (Salon Y). The address for (Salon Y) is (xxxxxxxxxxx) and appointments can be made by contacting (xxxxx) at (phone number). If you have any questions please feel free to contact me directly at (personal number). I look forward to continuing to be your personal stylist.
Best regards,
Xxxxxxx
