Photo Plan In Progress

I came up with a pretty decent price plan for what I feel comfortable charging and what I can offer without shame or any apprehensions. I want to offer 4 packages based off of this formula:

$20 for time

$10 per wardrobe change

$10 per photo retouch

$30 per full [unedited] CD of photoshoot

1. $60 Package
30 minute photoshoot
No wardrobe changes
4 photos selected on site by customer to be retouched
+ Full CD [unedited] an extra $30

2. $80 Package
30 minute photoshoot
1 wardrobe change
5 photos selected on site by customer to be retouched
+ Full CD [unedited] an extra $30

3. $100 Package ($10 savings)
30 minute photoshoot
1 wardrobe change
8 photos selected on site by customer to be retouched
+ Full CD [unedited] an extra $30

4. $140 ($10 savings)
30 minute shoot
2 wardrobe changes
8 photos selected on site by customer to be retouched
Full CD [unedited] included
