Keeping an octopus is an expensive proposition. The tank and pump and skimmer and other equipment costs hundreds of dollars. As you might guess, the food can be expensive, too. If you live near the ocean and can collect some (provided it's legal) or buy from bait stores, that can reduce the cost. Frozen shrimp is one of the best things to feed aside from live food like crabs.
You might start with a small salt water tank and learn all about keeping it. That would be less expensive and give you some good experience.
Look here for some actual figures on tanks:
