No because your wife and sons dependency are based on your employment visa and once that is gone then they cease to be dependents.
Setting up a company is an option, and then you would need to apply for a work visa in your name again, but the business plan would need to be sound with plans to employ locals, etc before immigration would allow a visa to be granted. This could take several months to set up and do.
