To fix those buttonholes, I'd just read Jeffrey's tutorial, get some gimp and silk twist, and put them in yourself. Do 10-15 on some practice cloth first (this should cost you $20 in materials and five hours). In effect, they're serged (badly), but unworked - as yet. You can still save this one so that it looks passable.
PS that's a nice birdseye. I have a length of 400 gram B/W myself that I'm waiting to make up.
