One of my colleagues teaches Spanish to foreigners. She has a degree in teaching languages, including Spanish, and speaks English as well. You might find her just right for you. Rather than publish her name and contact information here, I'd like you to PM me if you're interested in contacting her, and I can put the two of you in touch.
