E-mailing them to ask would probably be the most sensible course of action. If they aren't Candy Custard has a list of people offering sessions on her site and her studio / messy room is pretty impressive.
I thought they were fully operational again but I just found this message on the 'contact us' page
' NOTE: Unfortunately we are not able to arrange messy sessions at this time, however we are able to shoot custom videos for you. Visit Messy Angel for up to date contact details'
I'm sure if you PM the lovely Miss T she'll let you know what the situation is with sessions for Splosh A Girl as she still posts on here (hopefully she'll see this post).
Had some good sessions down there over the years with Scarlett, Messy Angel, Tori and Kate
