300lb 6’ guy looking for a cheap beginners gi

Hello, I’m just starting judo (I mainly train Muay Thai). I’m having trouble finding a gi that will fit my stomach without being for people 4+ inches taller than me. Is it best to buy one of these and have it hemmed to my height? Or is there somewhere to look? I’m hoping to keep it under $100 if possible. I may also use the gi for BJJ. Any tips? Thanks!
