4th Gen Pokeomon trading in SS

Hey guys.
I am new on this forum, myabe I post this thread in wrong topic so I apologise in advance.
On January this year I bought NDS LIte and some pokemon games.
Is there any way to evolve my pokemon who needs trading to change his form?
I heard servers of Nintendo are down, but I also heard there are some fan made ones?
Anybody here got an idea what to do and can help me with this problem?

I bought this console mostly for Pokemons so I will really appreciate giving me a solution :))

You are right about the DS servers being discontinued, it has been that way since 2014. Due to that, non-3DS games can only trade locally which means you need another person with the game or 2 DS systems.

If you don't have either of those, you're out of luck and would be better off upgrading to a 3DS and the 6th Gen (and soon 7th Gen) games if you want to mainly trade.
