Kuiu is kind of cheap compared to other brands. So eh.....
Custom rifles are a BS problem. I have custom rifles and I have Blasers that cost the same.
Buy a mid-grade rifle that shoots, and put a decent scope on it and be done. You can easily spend $1500-2200 and have everything you would ever need for 99% of the hunting you will ever do in your life. $750 Tikka and a $750 Leupold VX-III 30mm 4.5-14. Get a flat shooting caliber like 280, 270, 7mm, 30-06 or 300 and go kill stuff. If you are recoil sensitive get a 7mm-08, 308, 6.5 creedmoor and do the same.
Binos are more important than anything else and I still see dudes with cheap opera glasses in the woods. These blister pack Tasco 7x25 or 8x32. Sell all your guns and get a pair of binos in the $1000 range plus.
Boots are the second most important thing. You don't need a $600 pair, but you need a pair that works for you.
Rangefinder just needs to be accurate $250 Leupold or similar 1000 yard model, 1600 is nicer.
Spend the rest on tags and gas.
Taxidermy is also BS, use the rotting method to clean your skulls in the backyard in a $15 plastic tub.
Or buy a souvide machine and dunk it into a old plastic tub to speed things up $80.
