Try scheduling a day in advance if possible and around mid-day. Note that if they don't have a phone operator you may need to leave a message containing: name/referrals/appointment date-time/call back #. Do not mention anything concerning rates or sexual acts (see newbie guide).

Hopefully this helps. Have fun and stay safe!

I've found that e-mailing is the best way to make initial contact, and many providers will prefer it.  But if you decide to call instead, probably best to call in late morning or early afternoon.  Good luck!

to your e-mail at her convenience.  This has been much easier for me and I'm sure for the ladies.  Just be sure to be specific (date, time, length of appointment, incall/outcall, etc.) so she knows what you are looking for.  If you get too specific about anything other than "her time", you e-mail will most likely be deleted and you will not hear back from her.

and follow any instructions therein about how to best contact her.

I'd say that 90% of providers request email (or their email forms) for the initial contact.

You can then ask what would be the best time of day to call should you need to speak to her.
