The Hasselblad CFV 16 megapixel digital back will be within your budget. I've sold two within the last few months. Both sold for around the usd $4700.00 price range. The CFV uses CF cards.
Hasselblad/Imacon also made the V96C digital back which probably sells in the price range of $2500 to $3000 now. It is also a 16 megapixel but instead of CF cards it uses an image bank which stores the photos. If I remember correctly it can hold around 1200 photos. Someone can correct me on that if I'm in error. The image bank looks like a battery pack and my personal opinion is that you would appreciate the CFV digital back more than the V96C because of this reason.
You can also consider the old Kodak Pro Back Plus digital back. They should be selling in the 1500 to $2000 range these days I would imagine. They use CF cards as well but will have some age on them at this point. The last one I sold was brand new ( old stock ) and I sold it for $5000 but that was several years ago. They've not made them in a while so be careful if you buy one. On any digital back for the Hasselblad ask them if they have any dead pixels or any calibration problems. I've ran into these two problems on more than one occasion. They also made a "non-plus" version as well. Here is a former thread where they speak about the differences: http://photo.net/medium-format-photography-forum/00H7ve
You can also consider the Phase One backs but others here can provide more information for you on those I'm sure.
Lastly, you don't sound like you have any interest in doing so but you can order 120 film online and have it shipped to your country. I'm confident places like www.bhphoto.com will ship overseas. Or if you need some help acquiring the film I am glad to be a source for you. Just write to me privately and I'm glad to help secure some for you any time. I hate to see your film backs become a useless item for you. I'm sure you could also find someone to process for you as well and ship back to you but, again, others here might help you in that area more than me.
