>>11035as other posters have pointed out before, there really isn't much to be gained by paying money for things you can find yourself. i haven't tried it myself but i imagine the niche is rife with scammers. sometimes you just have to accept that you've exhausted your resources, and that waiting for more information to use can be just as helpful. check regularly and use multiple sources to confirm your information or leads, things change, information is added, and sometimes these online OSINT resources are shoddily maintained and bring up false positives. keep your information consolidated in a google doc or something like that.
you have part of his name, do you know a general region of where he lives? true truepeoplesearch, afaik you can enter a first or last name and it will still bring up records of people in that region with that name. pimeyes uses facial recognition and i've occasionally found more pictures and webpages that way.
do you know for a fact he has an instagram/facebook? these are generally pretty hard to dig on unless you have an email or a phone number, and most of the time i've had better luck finding accounts through their social circles. whatsmyname.app and epieos.com can be pretty useful in finding usernames and emails across different platforms too.
