Messaging someone I just met

I recently attended a week long leadership conference. At the end, we were able to leave notes for each other and I left one calling a girl beautiful with my phone number.

She texted me with:
Hey [my name]! It's [her name] I just wanted to thank you for the letter. Your very sweet and kind!

Considering I have had very little verbal interaction with her, how should I reply to seal a date?

I'll leave it to some like like Danny or Ruler to give you an answer, but I recommend having most of the conversation in person. Also, welcome to the forums. Don't forget to make a journal. Good luck, mate!
