Day of coordinator help!!!!!

Originally my fiancé and I were going to have some family do our venue decorating for us. We then decided to go with a day of coordinator because the family we were going to have do it are now a part of the wedding. I found one on Facebook who is trying to build her portfolio. She was offering 75% off if you booked her by the end of the year. I thought, wow, that’s great. So I contacted her. We spoke on the phone and I stated our wedding is June 6,2020. She again said she is running a 75% off deal and requires a $250 deposit when you sign the contract. We live about 4 1/2 hours away from where we are getting married so everything we’ve planned has been through email, scan and email, phone and online. We were supposed to be paying $400 total for her services. All we literally need is someone to decorate for us. We can take care of the breakdowns of everything and everything else. So she sent me the contract through email which I printed so I could sign and scan and email back. I printed the email and it stated the deposit is due by the end of the year. It also said our total is now $650. That’s $250 more then what she originally stated. I messaged her and questioned it. She said she’s talked to so many people and her special is if you are getting married this year. That wasn’t what she said from the beginning though. I talked to my fh about it and he didn’t want to go with her because she lied but even at $650 that seems like a great price. So we agreed we would book her. I signed the contract and emailed it back to her. She lives where we are getting married. Hurricane season is here which I completely understand. Right before the hurricane she stated she wasn’t going to be on her phone much in case she lost power. Again, I understand. She said she would be in contact with me as soon as the storm passed. It’s been over a week. I haven’t heard a single word from her but I’ve seen her posting things on a Facebook group page I’m part of in her area about needing a job. I can’t find any of her posts now about her day of coordinating services. Am I over reacting about being worried about this? Should I find another day of coordinator to help us and tell her we decided not to use her services? We haven’t given her the deposit yet. Our contract doesn’t explain what will happen if you back out except stating “in an event of a possible cancellation due to a natural disaster or death in the family, everything will be refunded except the initial deposit”. It doesn’t say if that is her cancelling because of that or us cancelling. I know we have time before we get married, but it’s only 9 months away!!! Wedding planning is stressful, but definitely going to be worth it.
