There is a neat little free archery spine computer program that will give you a tunable arrow within a few minutes, but there is a lot of info that has to be inputted and you didn't provide it. But there is a caveat. The info has to be correct or it won't work.

Things like, what is your draw length, the type of bowstring material (fast flight or dacron), how many strands in the bowstring, whether you bow's shelf is cut to center or past center and if past center, how much past center, 3 or 4 fletch and the length of the feathers you're shooting. Also and this is very important is, how thick is your strike plate.

All these things are needed. Once you have a tunable arrow, you can fine tune by adjusting the brace height either lower or higher from where it's set on your bow now.
