I have recently completed synthesis of luminol and am going to present it too my class tomorrow. Ive tried NaOCl and NaOH, but I suspect there are
better ways that I have available. How would I do it with H2O2, what concentration solution ought I use? And with the NaOCl and NaOH how much of
each should I use, in how much water, with how much luminol. Sorry, I'm asking for a hand out, but I don't have too terribly much luminol to
experiment with. I have low yields on the last steps, next time I think ill synthesize sodium dithionite instead of the janky Nurd-Rage way):

Just buy some thiourea dioxide, which is available as a chemical for dyeing (Either used to discharge dye from a cloth item or to reduce indigo before
dyeing) . I demonstrate the preparation of luminol using this reagent on my youtube channel.

I used Cu(II)Cl and .5% H2O2 in a .5 M NaOH solution, but thanks anyways(; I'm going to make a big batch this weekend and do something cool with it,
my chemistry teacher might let me violate the rule and use blood(;

That should be CuCl2. You don't need to give the oxidation states in the formula.

I know, but for some reason my fingers like to type it that way 
Also, for
future reference, the wiki says cyanides also catalyze the reaction, will cyanates and other similar anions work too?

Would a thiocyanide work?
