I just need to know a general amount of how much you would charge for a cake like this. Thanks!

It really depends on how big the tiers are.

Let's say the whole cake was about a foot tall, maybe a little bigger. With 8in and 10in rounds.

In the photo, it looks like 8 inches tall total (two 4" tall tiers).

$175. That cake feeds 50 @ $3.50/serving.

$175 sounds about right. I start 2 tier cakes at $150.

$241.50 for 6x4" and 8x4" cakes (feeds 26) if I'm making the booties and the custom board and wired stars and they are providing the bear topper. Another $25 if I'm making the bear topper.

It looks like 4" between tier sizes... perhaps an 8" tier with a 4" tier on top. Once you know how many servings you need, the industry standard 8 cu. in. serving chart can help you decide what size to make:
