Hi Robin,
Pleased to meet you. I'm from Ohio, but my husband and I are missionaries in Australia, so I'm far from 'home' at the moment.
It sounds like the Lord has blessed you with a lovely family. It's wonderful that you are able to home school them and be at home with them. I know it is a lot of work - but very worth it.
I hope the Lord will bless your online endeavors so that you will be able to build that house before you know it.
I took a look at the links in your signature. How long have you been at those? I've heard SFI mentioned in another forum, but really don't know what it entails. The sign up page isn't really informative enough to guess.
The other one sounds interesting.

Are people paying you to wear their logos? I suppose that would be okay if it was something you didn't mind advertising. I'll be interested in hearing how these are working for you.
Feel free to ask questions here if you need some help with anything specific. We all do our best to help when we know the right answers.

Blessings,
Angie
