Welcome,
Iras Sabir! Your character looks interesting and when reading the bio, I had a clear vision what kind of person she is.
Just one thing caught my attention, though: Lizzie's history implies that she has had her farm for a few years (at least) but she's not of age yet, being only 32. I wonder if she should be a bit older - unless it's a key point in your character that she is leading such an independent life so early, of course.
As to your idea of how Lizzie could be intoroduced, I think it looks like it would work and would be able to develop into a masterful comedy.
What do you others think?
