Second act help!

Hi everyone! Some advice please! I have had just 1 job all my life- yup started working at McDonald's when I was 16 and worked my way up thru the years (30+ years!). Now we are getting ready to move across the country and of course I will need a new career. My question is when do I start my search if I am hoping to start my new job in July, 2021. My husband thinks its time to post my resume now to see what is out there, I want to meet with a head hunter after the new year. Thoughts anyone?
