With that level of detail, you're looking at Selective Laser Sintering (SLS) or Direct Metal Printing (DMP) / Direct Metal Laser Sintering (DMLS), which will run into many tens of thousands or even more (I'm not that familiar with the price range, but it's right up there). Couple of providers include http://www.3dsystems.com and http://www.solidconcepts.com (a quick google search for "metal SLS printer" or "DMP printer" or "DMLS printer" will give you a few results).

A cheaper option may be to use a wax SLS printer and lost wax casting, but I don't know what level of detail you'll be able to get out of the casting process. You might be able to find one that fits your bill for under $10K.
