You could go to the wholesalers your self - I seem to no that "Sally" hair and eauty" is international so just go to sallyshairand beauty.com - and look for your local one

You don't have to be trade to buy from there the public can go in -
Look for a product called WELLA MAGMA - this product bleachs and colours at the same time - so you can get a l=colour wheich is vibrant red in one stage - It is kinder and safer than bleaching it then colouring it too.... Good luck hun
