In such a large room since the higher modal density comes down you don't need as much bass trap as smaller rooms. But you do need to control the rest (reverberation time and early reflections) which takes a lot of material.
But without making a model of that room one CANNOT guess.
Cheapest way to do this would be using DYI stuff. You can use foam as well, should be more expensive, send me an email for further information.
Avoid carpet unless you really have to use it.
