LinkedIn? No it's Instagram and Snapchat. look for a friend of a friend and message.... I think my son was the only guy on his team that had a LInkedIn account some years because he did internships-many guys just coach camps and play tourneys over the summer. For international players who dont go to flagship P5 schools with boosters happy to provide jobs, coaching may be the only job they can get in the summer if they stay in town. Remember most tennis players are not CS and engineering majors who can easily get work visas.
Searching UTR by location and messaging is still a very good option to possibly locate those post grads who have relocated to new cities. My son has been a paid hitting partner, and players have found him via word of mouth, UTR messaging, and even the PGA store. Son drove to PGA store with a teammate when it was rainy in the spring since his team didnt have indoor courts; there was a dad with a 14yo in store, saw him play, and asked if him would be interested in being hitting partner. My son did coach some in season but off campus. Even 2 hours a week helps pay for food.
Also could call or Email local academies and/or HS coaches for numbers of players currently in or graduated from college who might be interested in paid hits. Most players stay in touch with their coaches.
