It depends on what type of online tuition you want, subjects, DD’s needs.
You could look at You could look at SENsational tutors, Learn with SAT, Love2Learn, Hill tuition, South Coast tutors, The Wildheart foundation and Kite. Then there are tutors who focus on specific subjects, e.g for maths you could look at Claire Miller - maths positive, Laura does maths and Maths by Ian.
As an aside, the EOTAS package is going to be a proper comprehensive package, isn’t it? Not just a bit of online tuition (maybe with an hour of sport and OT thrown in? But a proper comprehensive package, including things like therapies, mentoring, accessing the community, exercise/sport, resources/equipment/subscriptions/memberships/a budget, professional time and depending on DD’s needs things like cookery/music/drama… and APs. Otherwise, when you have the right of appeal, you need to appeal.
