...Your client can review you. Based on what you said in your subject line it will probably be your first review. He will create your TER profile and after TER has approved and posted his review you will have a TER provider ID#. That is how TER works. You are a basic member when you register. Even if you post ads and post photos on the Photo only board. Even if you clicked you're a provider when you registered you are still a basic member until a client writes a review of his time with you. He submits it, TER approves it, and then TER posts it.
When he fills out the review form if it asks for your TER ID# (I don't think it will) he should leave it blank.
He can leave you a review by joining (registering) TER for free. Click on "Reviews" in the blue bar across the top of the page.Then click on "Submit a Review" which is on the far right just under the blue bar at the top. He then reads and agrees to the guidelines. When he clicks "Agree" he will be taken to the review form which he fills out with your information. When he's finished he clicks Submit. TER will check the review, approve it, and post it.
I have to let you know if he is a new member of TER because you are also new his review may be held up until he writes another review of another provider or until you get a review from another client. Both of you being new have no TER history and TER wants to be sure you are legit and he is also.
This is a catch 22 for newbies but it is how they often do things. You being reviewed by an established TER member would get your first review posted right away most of the time. A newbie reviewer will usually get his review posted right away when he reviews an established provider.
Read the first post at the top of this board. It's titled TER's Instruction Manuel (aka The Self-Help Center). You can click the link I've included to read the section about getting the Free VIP for Providers. Read the whole manual. It has answers to your questions.
