Looking for rhino iguana

Hello,
New to this site been searching around for a rhino/Cuban rock iguana for a month now. Currently looking for one that’s a baby or juvenile age. Seen a lot online and a lot our pricey. Looking to get one under 250 hopefully. Can make payments every two weeks with PayPal. Have everything needed for one. Mega ray lamps hides and caging. Wanted to start one in a 40 gal breeder tank and once big enough put in my custom made iguana cage. I had a green iguana before was over 5 feet. Was a aggressive male that I had to make a hospital visit. I got bitten real bad. With his behavior had to have him put down. Tried find him a new home but being honest about him. No one came around and was giving him away for free.
But if anyone can point me in right direction would be appreciated. Kinda lost hope with the rhino/rock iguanas because they are so high priced. Have everything needed to House one of these guys. But not enough money to buy one lol. Just being honest but hopefully maybe soon. Feeding and vet bills aren’t a worry. Vet I use with checkups is great! He pointed me in right direction with my green iguana. Just bad memory I don’t wanna cross again. Broke my heart to have him put down. Looking forward to any response thanks have a awesome day ahead!
