how long is too long....UPDATED

...to wait for a vendor to respond to you??? When do you decide to give up and pick another person to work with???

Specifically I am talking about Oksana. We emailed last week and literally one week ago to date I sent her a few available dates to schedule a trial....i have not yet heard back! Do i try again or do I say it isnt meant to be and find someone else?
From what I am reading on these boards there are a ton of other good makeup people on here so do i wait to hear from her (try her again) and book with her bc she seems to be one of the best, or do i say i prefer good customer service combined with good makeup???

Im leaning towards moving on....so many options out there...i am considering:
sandra baldini
Kelly - glam me up
M * I * A
lola loves makeup
Cosmetic Artistry MYA

thoughts?!?

********Ok update 7/23...I emailed Sandra baldini and Mya cosmetic Artistry yesterday morning and still no response! I swear i would think me email is not working except that i am still getting email from friends and a ton of other junk mail. is it me?!?! is it the date??!?! so frustrated! Next on my list...M * I * A* and Kelly from Glam Me Up....
