may I offer a helping hand check out Brownells they have alot of 1911 parts pretty much everything you need to build the only draw back is the Lower reciever will have to be shipped to a FFL dealer in your area. the rest it is pretty simple infact most of the gun can disassembled with the hammer spur. just use brass punches to remove some pins and rubber hammer or brass hammer to put pins in and ofcourse the finish will have to be done. and then choosing the rear sight. brownells has millet adjustable sights or you can go with tru glow night sights.
just check them out here is the link: http://www.brownells.com/
good luck and besafe and Merry Christmas and Happy New Year
