Hi Lucille!
If you're going to Kent, if you live near a train station or commuting coach, from a lot of areas in Kent you can travel to London within 1 hour, so there's a lot of areas you could possibly work. Might be an idea to look on various job websites (Indeed, Simply hired, Total jobs, Monster etc) in areas that you are living/are thinking of living (such as Kent) + searching for recruitment agencies that deal with your type of experience and see if there are any vacancies that you have experience in/think you can do as some areas will have more vacancies available that you might be able to do. If after looking a bit in certain areas, if there doesn't seem to be much around, then maybe not worth thinking of moving to that area.
