If you paying for tutors (or together with other families, hiring a teacher), you are running an alternative school, not home schooling. You will also discover why schools are cost-effective, especially if both parents can work full time (bluntly tuition is much less than what one can earn working with the time that one is not home schooling).
If you are truely “out of town” and there is no acceptable school locally, you have to home school. The question is then whether the parents have the background to cover all subjects, including Torah subjects. While there are “canned” curriculum for secular subjects, they need to be adapted for use with frum kids, and there is no “canned” curriculum for Limudei kodesh.
