Your hair may have turned orange because you need not leave the bleach (from the highlighting kit) on long enough. Whilst you still have the bleach on, your hair goes through different colour stage. This is normal. The bleach is stripping out colours from the hair one by one. Hair colour is built in layers. It starts off with the darkest. So for an example I have black hair. When I apply bleach, it will first strip out the black, then the underlying colours. The next colour that will be stripped out is brown, then goes to a reddish colour, then orange, then dark blonde and so on. And because your hair is now long, you might have not applied the bleach correctly and long enough. (Sorry about all that, just thought it's vital info for when you next colour your hair
)
You will need to see a professional but as you say they are asking for a lot of money, try going to a local hairdressing college. It's quite cheap and they know what they're doing. If they weren't capable the teachers would not let them do it.
