Legit Backlinks to Boost Domain Authority

My site is brand-new, so I need a set of legitimate, white-hat backlinks to give its domain authority an early lift and help it start showing up organically. The only thing I care about right now is acquiring real backlinks, nothing spammy, nothing generated by bots, and absolutely no PBNs...
