Advice on dating my tutor please?

[Josh]

I'm a freshman in college and unfortunately I need a tutor for my Spanish class. A fellow advertised tutoring on Facebook and she's really attractive. The only problem is she charges $30 an hour. That is a little too pricey for me. While I could use a little help in Spanish, she is really cute and I'd be interested in possibly asking her out. Is this frowned upon? Also, is a one hour session long enough to get to know her a bit before I do? I'd really prefer not to spend more than $30 to get possibly rejected. Any tips would be welcome. Thank you.
