OP, you need to have a prospective tutor identified before making such a plan. Because the success of your plan is heavily dependent on the tutor.
My friend tried it last year for her PG 2e son who was under challenged in school even with acceleration. In her case, it did not work out because the tutor was not taking her son's education "seriously enough" according to her. She expected rigor and advancement in several subjects which did not happen. She was especially unhappy about the science content which was light. But, my friend was hands off in the curriculum design and lesson plans and expected the tutor to take care of it all.
My friend also expected a lot of "extras" like computer programming, art and craft etc which was not happening either. So, she fired her tutor and has hired a nanny to drive her son to various tutors and co-ops and now he seems to be getting the instruction at his level. And I hear that it is a lot cheaper than a full time tutor.
Hope this helps!
