Help with desoldering/soldering ecu

Hi, Im looking for someone who can install a pin header on my ecu. I wanted to do it myself but i’d rather not attempt it with the crap equipment I have.
I’m not gonna spend $200+ for special equipment i’m only gonna use once.
If you know a place or shop that works on electronics/circuit boards(video game console modding?), let me know. k thnx.
