To dye or not to dye, that is the question....

Hey guys,

I am having a dilemma. I have grown out my bleach - it's got very very blonde streaks at the front and the rest is a deliberate strawberry/reddish blonde as I was ginger last year. I have been being extremely extremely good and not dyeing it for over a year so ended up with an accidental ombre whilst I tried to get a job. I desperately want to dye it - got the dyes, they're sitting in my cupboard, Manic Panic's devilish, SFX napalm and electric banana. I was thinking of a flame effect.
I don't have a job, currently can't even seem to get an interview and i really don't feel like me with natural coloured hair. I know the jobcentre are possibly not going to be best pleased but also, I was sort of thinking of heading along to a recruitment thing at an alternative modelling agency on Thursday where i think it might help me to get on their books. And I can always dye over it/wear a wig....
Should I dye it? I've been umming and ahhing about it all day and i'm no closer to a decision....  :-
I wouldn't need to bleach the midlengths as it's orange toned blonde anyway but if i was to dye the whole of the bottom orange would I have trouble with putting in yellow on the very ends later?

Cheers!
