Not much info to go on based on your OP, but here goes anyway.
If all you said was "her review are what I’m looking for" you're already THAT guy. If you want to chit chat, go to a coffee shop. If you want to meet a provider, suggest a date, time, and location (along with anything else she requires on introduction.
Beyond that, be sure to review her website or ad to verify the proper way to contact. Some want their online booking form, some text, some PM, some email. They don't all check all these all the time. If you feel compelled to reach out by more than one method at a time, make sure she knows that, for instance, you sent an email, but texted also, saying hey provider x, I just sent you an introductory email from
[email protected] You "haven't heard back"? How long has it been? If I'm right about my first issue that she thought it was chit-chat, you may never get a response. If you actually made more of a serious inquiry, give her at least 48 hours. If you're getting blue balls waiting, pick someone else. It's still a free country. If she eventually responds, Pick another date that works for both of you. If none of those things happen, wait a week or two and try once more.
If I am very interested in seeing a provider and on a specific date, I'll also request that she respond by a specific time, otherwise I'll assume she's not available. that way, I'm not up at 3AM wondering why she hasn't gotten back to me yet.
