People do everything part time at home, from babysit neighbor kids after school to making cupcakes to writing user documentation to maintaining websites to programming apps to sewing window treatments to songwriting. All or more or none of these may fit OP's interests or skill set or contact network.
I worked from home for maybe ten years doing complex editorial work after working for a publisher (and before going back to the office). I loved it, and I never looked for projects; people contacted me. I wish I had a nickel for all the people who said they could do that work too. Um, no, they couldn't, no more than I could do custom website graphic design today, no matter how many opportunities there might be, because a., I would hate it, and b., I don't know how to do it. So my advice is to OP is figure out where her skills and interests are first, and go from there.
