If I do not have an opening, I can help you find other providers who may be able to care for your children.
I belong to LEEP (Lincoln Early Education Professionals) and I can send an e-mail out to all our members telling them you need care. If someone has an opening, you could set up an interview to see if they would be a good match for your needs.
