we have no info on this car, but from what you describe i'd go with what the last garage has said , flush the engine and put a new/used turbo on it and take the chance. Alot of times when aturbo fails,some pieces will go out the exaust and very few gointo the engine. so i'd try that. YOu might try to find a used turbo to save costs. Also i'dhighly reccomend using synthetic oil with this due to heat in turbo.

one other thing i forgot to mention, make absolutely sure when teh old turbo is pulled off that the engine is cranked that particles if in the piston area are either sucked out with a vacuum cleaner or blown out by compression. You don' t want that crap going into the new/used turbo blades as it could damage them. then you would have the same problem. If you can you might look in a junkyard/wrecking yard for a used turbo, it may be cheaper and you may get one that has less mileage adn still in good shape. But again i can't stress enough to use synthetic oil in these vehicles, the turbo spins very fast and builds up a lot of heat. also when you shut the car off just don't turn it off, let it idle down for a minute or so so the turbo can slow down if at all possible.
