I'm sure there will be some carpenter out there that will take up the job. but lets face it, unless you are a friend of the carpenter, they will be charging quite high, making it very 'bo hua' just to do the doors. you might find yourself in the next 2 situations: 1) the good and reputable carpenters will not take up the proj as they are better off taking up other bigger proj. 2) those that are willing to take up will have to charge significantly higher as there is no economies of scales.
