First off, everyone calm their tits.
Second off, I run a Recaro Pole Position ABE, it was roughly $1400 CAD, with the exchange rate, that is probably close to $1000 USD, you can do the math. That is seat alone, since you didn't specify total cost, not sure you've considered that you will need a mount for it. I am running Buddy Club Super low down mount (I believe fixed back only) $150 usd maybe? Thirdly you will need a resistor for the drivers seat to trick the airbag, few bucks or about $30 for one that fits the factory plug. Lastly the passenger seat will give you tons of headache with the occupancy sensor and will require a much more in depth solution if you don't want to look at the airbag light the whole time, think someone has this and it will cost a few hundred bucks.
The Pole Position ABE are designed for working in stock cars with stock seat belts. They are not FIA compliant and since again you have given zero detail on the use of the seat other then "sitting in", I presume it is just show, so this would work for you. You can get an extender and run it up through the hole for the buckle, I just have mine on the outside and it works perfectly fine, no fear of submarining.
Now fly little bird and go find your seat.
