If you want to earn more seed tickets go to Renter you can at least farm seed tickets 70-100+ depends on how fast you farm.
Going on in the suggestion it's more better to make a map for farming zeny using crimson rose because that map belongs for the new player to the server. That's where they are warped at first and level themselves up, they might get mad if a zeny farmer goes there and kill all the monster in the map and they can't level so it's better to create a map full of monsters same as the seed/berry room/dungeon.
