SSW visa, construction

I work in construction as an electrician specifically on IT systems. I don’t have a license yet, I’m still an apprentice, but I am interested in getting an SSW visa. Has anyone else gone the construction route that can talk about their experience?
1. What is your trade/job? (Or did you get a new one when you went to Japan)
2. How long did you do it in your home country before moving?
3. How did you go about finding a sponsor? Did they support you?

I would say I get 1-2% better at Japanese every day btw, I study daily for an hour

Thanks
