What to say in a 1st text after meeting and asking a girl out?

I met this hairstylist at a hair salon. As she started getting me a haircut, she asked about my life and what i do. We had a good conversation. When she finished cutting my hair, I asked her if she would mind if I ask her out. She turned her face, smiled blush and asked me “Tonight?!”, i responded “not tonight, just anytime you want, how about you give me your number and we’ll text?” she wrote her number and handed to me right away. Now it’s been exactly a day, and haven’t texted her yet.
1) Would you please suggest any good 1st text samples to send?
2) How long should I wait to shoot her a text?

Thank you guys a lot, your answers are appreciated!
