L-1 is for intracompany transfers, and you have to have worked for the company for at least a year outside the country to qualify for that.

To be honest, if the job doesn't qualify for TN-1 (NAFTA), there isn't much chance of getting any sort of work visa. H-1B is the only other possible option but the quota is oversubscribed by now so you wouldn't be able to get one of those either. Even if it wasn't, it requires labour certification that the employer can't find someone locally to do the job, and that isn't likely from the sounds of it.

The US immigration system doesn't favour workers working in non-professional positions, I'm afraid.

the ones who "just pick up and move" do it illegally. I wouldn't recommend that route.

the only visa you could get while in the US is possibly a marriage based Green Card. Unless you already have an established relationship with a US citizen, I wouldn't recommend that route either.
