Cheapest way for image to video generations using seedance?

Hi, i am relatively new to the entire Ai stuff and i noticed that i can create some really nice nsfw image to video generations using seedance 1.5 pro? At the moment i am using it on atlascloud and i was wondering which is the cheapest method to use it? Are there any other websites that offer lower prices? Or is renting a gpu easier? If yes, can someone explain to me how i could do that? Thank you!
