$100 for a guide that might not work on my wifi only iPad is a bit steep, plus random people stop saying this guys fake or a scammer he's been on this groip longer than you so stop sending me messages

Ok new to this page, ok I have a wifi only iPad which is iCloud locked to original owner tried these companies online which are all fake a cost me a lot of money, what service do you suggest I buy? I'm also looking for a gsx sold to account for my mate who owns a phone repair shop where I live, but my priority is getting this wifi only iPad unlocked from iCloud first.
