Working as a life coach for a company or another coaching business

I’m currently completing my life coach certification with another school and seeking opportunities to work for a business/company or another coaching business as a life coach.
I prefer to start at this level while I continue to build up my own practice.

Is there a list of resources or articles that can help with getting this search started?
Any other suggestions for continuing to practice as a life coach before jumping into building out your own practice?
