Seeking evening babysitter for 3 kids

We live in Riehen Dorf and are looking for an evening babysitter 2-3 weeknights per week for our three children. Looking for someone with 5+ years experience with both babies and kindergarten/primary school children, ideally both English and German speaking. (Fluent English is a must.) Potential to expand to more hours based on how things go. Would also appreciate someone who might be available for 1-2 Sunday afternoons per month, but that is a “nice to have”.
