When is the best time to send the first message after getting a tinder match at 6:00 am on a Thursday?

I 30's Male got a tinder match notification from (25F). I don't know when it is ok to send the first message. I have a job, but I don't want to send her a message and her feeling like I got don't have a job. I don't want to send a message to seem desperate, but I don't want her to think I am not interested.

How long should I wait to send a message? Should do it on my lunch break? Help!
