So I would buy a basic Brompton in the colour you wanted and then sell off the parts you don't need. A basic single speed with no fenders or racks etc. This way it would be cheaper than trying to acquire the basic frame and fork.
Again if I had the choice to do it again, I would be an extralight version second hand because they are almost impossible, at least in Canada to purchase that version. Then sell off all the parts I didn't need.
Good luck with your project, it sounds fun.
