mua won't respond about contract

I was so excited earlier this week because the makeup artist I wanted responded saying she was available for my date! She was recommended by a family friend that used her a few weeks ago. She sent over the contract for me to sign and requested that the deposit be sent by venmo, so I did all of that. The whole conversation and payment happened on Tuesday. I've asked her 3 times since then to confirm she received everything and to see if she could send me back the contract with her signature for my records. Any time I message about the contract she doesn't answer, but when I messaged her about something else she responded immediately. Am I being paranoid? I'm starting to get a little sketched out by the situation. How long should I give her before I become pushy?
