I assumed you were talking about a NL tournament, not fixed limit. With those chips and a T$1,000 stack, blinds would increase something like 5/10, 10/20, 15/30, 25/50, 50/100, 75/150, 100/200, 150/300, 200/400, etc. (or maybe a little slower like SB of 5, 10, 15, 20, 30, 40, 50, 75, etc.)

To add more chips, I would suggest only 4 total denoms for a tourney set (unless you're going to have a very large number of players). So in this case you could add some $500s on top. You're probably not going to be able to support a starting stack bigger than $1,500 or so with $5 as your lowest denom. If you want a larger start, then you're probably looking at $25 as your minimum.

For example, here's a configuration that works --

300 chip set:
80 x $25
140 x $100
50 x $500
30 x $1,000

Starting stack of T$5,000:
8 x $25
13 x $100
3 x $500
2 x $1,000
total 26 chips each.

This will support 10 players, though there are not quite enough chips to color up everything with that number of players. But people just keep a few $100s at the end.
