Hi everyone, I am just awaiting my PCO Licence and looking to get started straight away within the Caterham, Croydon, Crawley area when it arrives, a couple of questions for you all. 1. What company is best to use for rental? 2. What is the average daily potential earning? 3. Is Gatwick Airport a good earner? 4. Is it viable working evenings only alongside a day job or working Uber Full time and quitting the day job? thanks
