you should try doing it all on a home server? you can run minikube on your laptop, or on an old upgraded PC, .. the thing is, hosting is so overpriced, you wouldnt believe some of the server bills ive seen, and this is what can break a project (wasteful costs).

tho I know your internet is slow, is it possible to spend on faster internet because it would enable you to run more services *and be fast for everything you do..

if not, yeah you should rent a VPS and run minikube on that instead.
