Bought everything when "On sale" at Menards. Are you near Menards? Familiar with it? They help with all the design work and do a complete project material list with costs. I gave them my hand-drawn plans, and we went from there. I'm not a builder, I'm an elementary classroom teacher (retired). They also designed my trusses and had them built at Menard's Midwest Mfg center in OH. Then shipped here and dropped on the wk site. Materials were also assembled and dropped at the wk site. If the order is over $2,000, all of these services are no charge.
