Text is always the best way to communicate with the Booker

since your a newbie and you have no refs or your cell# is not a valid # to a booker. They most likely
will not answer.

you ask why? are you le? are you a black-list? are you a previous customer w/issues?

I'm not saying you are just giving examples.

most bookers would respond to a text by requesting certain info to start the screening process. If you have been continuously  
calling them while they have been trying to work its not inconceivable you have been blocked. Bottom line bookers accept new clients every day if you have not gotten a response that should raise a red flag,

Thanks guys.

If you are confident the booker number is legit (see reviews against #)
call! if no answer send a text "I would like to make an appointment... here is all my info..."
don't wait to be asked for it, you may NEVER be asked. If the number is legit, no reason to wait to provide info. They will know you are serious. Make sure you provide enough info to be screened outright.
wait... a few days go by... repeat. This has worked a few times to get someone to pick up the other end of the line.
