We were in the same situation 18 months ago - BEWARE of people who claim to be able to help as we lost some money when basically an airline accepted the bikes but insisted we also had tickets which we brought, then 2 days before departure the airline refused to accept the bikes at the airport due to them being classed as dangerous cargo, we couldn't get a full refund on our tickets.
In the end we used Kaulston racing who import/export foreign bikes and they arranged it all - tickets, customs etc. Cannot highly recommend them enough.
Theres also a guy based in Delhi who writes for the BIKE India magazine called Bunny - his details are listed in the community section I think, and he is also on hand to help bikers in return of some photos of yor bike.
If you get stuck then contact me as I may still have their numbers somewhere.
