Start where you are.  Don't worry, Just discover!
Whether you are working full-time, part-time, in the home, out of the home or are home full time with your kiddos.  Considering homeschooling does NOT start with a dramatic life make-over.
Just begin turning over shells to see what you find.
Once you are in the process of discovery, the journey you take will uncover itself.  I promise.  There are women and men who have found inspiration when simply researching homeschooling and they find that that inspiration gives birth to new ideas of how they want to prioritize things and lifestyle, etc.  For some women, it's meant beginning a career instead of ending it, for some, it means moving, for some, it means realizing their status quo is perfect for them.  Don't worry, just Discover!
Here is a resource list for homeschooling:

Surviving Your First Year of Homeschooling

This resource, to me, was a light shining in a huge vast ocean of way too much information.  It is not from a specific faith background, so I know it will relate to any of you reading this.

A second resource that is amazing is to find someone in your area or someone at all that holds an "umbrella school" for homeschoolers.  That simply means that you can register with them (give them your name, kids names, and about $50-100) and voila!  Your kids are now enrolled in a "Private School" which precludes the need to do any other paperwork with your school district. 

Another amazing resource that is essential for your beginning is the HSLDA website to research the laws in your state.
