First of all understand it doesn't have to be all-or-nothing. Many homeschooling parents enroll in a part-time education co-op with other likeminded parents. I guarantee there's one near you right now. In these groups you essentially take turns teaching. There's almost always a parent there who is competent in an area where you lack expertise. It really just works out. The late-game strategy that I see is enrolling in community college for advanced classes in math, physics, science, etc. In Washington state you can start this your junior year in a program called "Running Start" and it's free. At this point your homeschooling with that child is essentially over and they're taking college classes for college credit.
