Based on some incredibly cursory pre-coffee googling, it would be about $1200 for the ticket (assuming you want a decent private-ish berth), probably around $500 for a GoPro and various equipment (a way to mount it on the window, spare batteries, chargers, memory, etc.) and somewhere in the neighborhood of $800 for the flight back (I wouldn't want to subject you to eight hours on an S7 flight.)

$2500 is a pretty reasonable goal to throw up on a crowdfunding website.
