New to raw feeding/ where do i start??

I have a 12 week old, female border collie x Labrador mix. I would like to mix in some raw feeding into her diet/ possibly entirely make it her whole diet. But i dont know where to start??

Ive seen subscription services to dog food, are these any good? Any recommendations?

How much veg/fruit do i feed her and how much meat?

What sort of meal examples do yous have?

Theres so much info out there, but its all so contradicting so i really dont know where to begin so id love to her your personal stories/ suggestions!

Based in uk/ireland

thank you
