Sponsorship has several different meanings.
There are cases where journalists and even blog writers get free hotel stays, in the expectation that they will write (positively) about their sponsors. But to get into that, one needs to be a recognized influencer to start with. First you need a successful blog, then maybe there will be some invitations and perks.
We can't help you getting that. And it is probably difficult in the Corona age, anyway.
