All you need to do is:
#1. Take out the Camp and island of good south of your first dungeon entrance.
#2. Connect the hero portal and entrance with a few labyrinth-like passages in your dungeon and fill them with traps, connect them to the guardroom/graveyard, etc.
#3.1. Rescue Talya before she dies.
#3.2. Do NOT destroy the last stronghold near Thalos, (that's the building that is spawning heroes that he send through the hero portal.)
After #3 it will get annoying I'm afraid, you need to guide here away from Thanos and to your first island of evil near the dungeon entrance and leave her alone.
That's it.
Now all you need to do is to use your creatures and traps and kill the heroes until you get the achievement, After the forest part near the first hero camp the fireballs will not rain down on Thalia so she will be safe. (You can spare a few creatures to guard her if you want)
The top right part of the dungeon has a diamond vein so dig straight east of the first dungeon entrance until you hit the dragon's nest, kill the dragons and dig out the room a little and your gold problems are solved.
As for the annoying part, Thanya will keep on nagging you to take her to the dungeon heart in order to escape Thanos, just ignore her. The moment she enters the dungeon the mission is complete so don't let her in until you got the achievement.

Done in the "Light and Shadow" level. There aren't 100 Heroes on the surface so you'll need to let the game spawn invaders to attack you if you want to reach 100 Heroes before time runs out. Scattered throughout the level are packs of Heroes as well as Hero camps. Keep all hero camps alive so they keep spawning Heroes to reclaim Islands of Good and invade your dungeon. It's entirely possible to get 100 Heroes within 60 minutes and if you don't do it in 60 minutes you lose the level anyway. It is recommended you make saves and attempt this and Prison Break separately.
The image above shows 100 Heroes being killed at just past the 6 minute marker, which breaks Prison Break. It's not recommended that you do Prison Break and I need a hero! together but nevertheless it's possible to get both trophies in 1 session. You must still keep all the Hero camps alive, then assemble a 10-creature army with the Grave Golem to invade the main castle area at the 35-40 minute mark. There is no mini-boss battle, only standard units and castle towers, even though Tanos is standing there with Thalya.
Once your army reaches Tanos, Thalya is automatically freed. Quickly cast Demon Gate to return your creatures to the dungeon while the characters talk. In a few seconds, you gain control of Thalya but any creature left behind will be killed hence the quick Demon Gate. Leave her there and ignore her whining, letting the game continue. The heroes will continue to spawn from Hero camps to invade your dungeon. Keep farming Heroes until you get the trophy. You can't do this if you already destroyed the Hero camps.
