?2.5k sounds about right... I am still dalaying finishing mine... (already paid for root canal and a crown on the stupid tooth and then paid to have it extracted :-( ) you can spread out the payments as the various parts of the process can take months to heal. My dentist did say they need to make sure you have good gums and decent bone in order to be able to do the implant, its not right, for everyone. My brother went for a cheaper option which was a bridge, i think its less invasive as they attach a new tooth to the one next door, but i think there is more risk of damaging the good tooth. Good luck.
