I cannot figure out how to hire a photographer.

I purchased the Moschino pack.  It has the option to do fashion photography.  I do not want my sim to be the photographer, I want her to be the subject of the photos.  I created a studio and a photographer, makeup artist, and stylist all showed up.  I got my sim ready and then tried to hire the photographer on site, but there is no option to do so and if I try to go to the picture station to have my photos taken, it just says that I haven't hired a photographer.  Well, he's standing there on the lot.  How do I hire him???  I checked the phone but it says I have to be on my home lot.  I don't want to live at the photography studio.  When I click on him and click the photography options, there is only options to discuss photography with him, not to get my photos taken.  Where is the option to hire photographers at the photo studio? 

Back in the day before digital cameras, you used to be able to go to a store like JC Penney and pay to have family pictures taken.  What I want to do with my sim is similar to that.  But it's not working.  Is this something I can do in Sims 4 or not?
