PLEASE.HELP. ash green hair mistake

Hello! I dye my hair a lot and I had at the time a black under my bangs, red ontop and blonde underneath. The red was a lighter orangy red. I wanted to get rid of all of it and go back to a blonde Color. I bleached the black and red twice then (my mistake) put an ash blonde over top. My hair is greenish gray and also has a bit of red shining through. It is a bit blotchy. I can not go to a salon I don't have the money for that and I need something quick and easy because I'm very picky and ADD about my hair and Color... lol. My Color right now is a medium dark blonde that has a green gray tint. The green and gray tint is very light. Looks like a very faded out Color. I was thinking about dying it a dark golden blonde over top with a red base? If I'm correct I think it will cover it. My hair is not terribly damaged but id rather not damage it even more with bleaches and Color oops like products. Really i dont care what color it will be brown red or blonde i just need it to not look green!!Please help!
