How can I push my seafood to the hotel and buy it back?

You aim at the hotel first, and it's better to open it. There are buyers, you can find out who they are, and then find someone to eat a meal, give them a little profit, and let them buy the seafood of the hotel, all of which are yours.

Or a bigger hotel, talk to the manager of their daily management, and it is best to give someone something beneficial to let him cooperate with you in business.
