Craft Staff Question, Please Help

[Thron]

So, I was looking to have a wizard of mine pay someone to craft a staff for him. It would have the following spells:

Level 2: Invisibility, Scorching Ray
Level 1: Magic Missile, Grease

I priced it as follows:

400 x 2 (spell level) x 3 (min caster level for a level 2 spell) = 2,400 gp for the first Level 2 spell.

300 x 2 (spell level) x 3 (min caster level for a level 2 spell) = 1,800 for 2nd Level 2 spell.

200 x 1 (spell level) x 1 (min caster level for a level 1 spell) = 200 per level 1 spell.

For a grand total of: 4,600 gp.

My questions are:

1) Did I do the pricing calculations correct?
2) The total price calculated...is that the cost to craft or the final total cost? My assumption is it is the crafting cost, so that to purchase it would cost 9,200 gp, but then again, I am not 100% positive.

Any help would be greatly appreciated, as my brief search fu after a 12 hour night shift is very much depleted.

I Think all the spells on the staff need the same caster level on creation. And minimum caster level for staffs is 8.

There are 2 things about crafting staves you missed.

First all spells in the staff need the to have the same caster level and second the minimum caster level for spells in staves is 8.

So what you're looking at for a cost is

400 x 2 x 8 = 6400
300 x 2 x 8 = 4800
200 x 1 x 8 = 1600

for a grand total of 14,400.

Staves are expensive.

Yeah, it may seem like Staves are rediculusly expensive, but keep in mind, they can be recharged for free. That is HUGE.
