Part time jobs for 15yrs old?

Hiii I’m 15-16yrs old and I want to find a part time job but half of the jobs either require O lvls certificate/need commitment for at least 3months…I’m planning to only work during the March/June holidays and preferably somewhere in the east(idm any type of work)If anyone has recommendations lmk☹️

(Also before anyone comments that I should go study or enjoy first, I just want to work to earn some extra cash for my new house/go vacation and help out with my parents🥹)
