A great way to learn and gain satisfaction
It may be true that in the long run you may not save any money building your own, if you quantify your own labor time. But the learning experience will put you way ahead of others. The advice about getting a used 1911 and modifying it to your own specifications is sound. It will provide you with a base to work and learn from. I don't know if they still publish it but the manual from Jerry Kuhnhausen (The Colt 45 Automatic- A shop manual) is a terrific start. I don't know if the manual is updated with series 80 info but for me that's OK since I don't own any series 80 1911's. There are also a load of Youtube videos, but I never know the credentials of who makes them so be careful. Anyway, I would encourage you to read up first and then go ahead if you feel it is for you. Good luck.
