Best Service Based Business Ideas Eu

Im interested in starting a service based physical business because to me that seems more promising than starting an online business. Ive looked online but can only find very few eu service based businesses. But i do come across loads of us starter business ideas which sound like they would do terribly in europe ( for example window cleaning, taking out peoples trash, pet waste cleaning etc.). So do you guys have any business ideas that work in europe as well. Start capital should also preferably not be that high (less than 15k if possible).

Im located in germany
