We weren't planning to have a two income home anyway - I was planning to be a full time mom for my kids even if they were away at a public or charter school. My mom went back to work when i was in fourth grade and from then on I came home watched too much TV and put off doing my homework. I don't want my kids spending that much time without a parent around - I don't think it's healthy for them or for my relationship with them. Besides, whether they admit it or not, even teenagers want their moms around, just out of their hair. :)
Good for you...that is the first gate, it seems to me. The next gate is your commitment...your willingness to go the long haul. There are a number of great resources available to you. I teach a high school class during my lunch hour two days a week. Relevance? It is in a Homeschool enrichment program, serving 800+ kids (and their families) two days a week. I have 11 highschoolers, some who have been homeschooled all their lives...and they love it. They are well-rounded, bright, excited abouot education, and certainly "socialized" well.
The school also has a support group for the families, particularly the Moms...assisting them in dealing with all of the vagaries of homeschooling. Let me know if you need more information.
