Welcome to ChipTalk!
I'd say your chip set is a little heavy on the 100s and a little weak on the 500s.
Here's what I have (and found it quite useful):
140 x T25
180 x T100
130 x T500
50 x T1000
Also, unless I'm missing something your starting stacks add up to T4000. Here's my T5000 breakdown using the above chip set:
8 x T25
13 x T100
5 x T500
1 x T1000
You could also use 12-12-5-1 or 8-8-4-2
15 minute blinds can make things turn into a push-fest relatively quickly especially in the later stages. But if you're under a time constraint, this is better than not playing at all!!

Your blinds increase too fast for my taste (doubling the first 4 levels). Here's the schedule I use (20 minutes at each level):
25 50
50 100
75 150
100 200
150 300
Break and Color Up
200 400
300 600
400 800
600 1200
800 1600
Break and Color Up
1000 2000 (With 10 players, should end around here)
1500 3000
2000 4000
2500 5000
3000 6000
Sometimes we don't even make it to the 800/1600 level and we made it to 2000/4000 once.
Best of luck and again, welcome aboard! Say goodbye to your paychecks!
