Training is the biggest issue: because you only influence indirectly other managers. The biggest countries have what it takes to establish an appropriate "scouting unit".
What I think is that India (or Prathet Thai) only a have a restricted number of users. But... can still create a sort of similar unit based on a small number of players. Quality is more important than quantity. Focus on the most promising players in the hand of the most cooperative general managers is the basis on which we should build. According to my "small country experience", people don't have the time & the sufficient motivation to jump in a major scale program.
Not to offense, but from what I saw since I'm here, the only player capable of assuming this role is Samurai_Tungi. The others only come once in a while. Plus, they don't have the background training knowledge required to optimize ones player potential. No misunderstanding tough: they are, in their ways, important to develop this community, but this is another debate.
