BrokenHorn, $650ish is just for the parts, $300-350 for an action and about the same for a quality barrel. Smithing can vary from one to the next but you should be able to get an action, get it trued, and the barrel fitted and chambered for $1200 or less. Places like Pac-Nor can do everything you want done if you don't mind shipping them the action. Pac-Nor
There are also some quality smiths here you could e-mail them for more accurate prices.
