Hey man, I recommend a size 70/10 or 65/9 needle, sharp point (schmetz microtex), and regular weight 100% poly guttermans, or the tex 24 hydrophobe that thru-hiker sells.
Any random home machine is capable of sewing it, but just make sure it has a good even feed, and that you have a very strong understanding of upper and lower thread tension if you want professional results.
Otherwise, I take on random sewing and prototyping projects for people here, and I'm sure some others will also, for reasonable prices. Although maybe not SE asian alteration shop prices. ;)
