How do I suppose to get into the team?

I know these question has been asked many time but non of these suit me which move to Thailand. (These questions are from me and my friend since I'm the only one who got reddit)

After 5 month of Karting I got the fastest lap of all time at my local track (in Thailand). And I'm thinking about joining a Karting competition but I got no team to support me any suggestions?

Is it better to buy your own kart? (If yes any recommendations?)
