I have a traveling set of 300 pieces that can be used for a T1000 tournament.

If you can convince your players to go to a standard T1000 tourney, starting with blinds of 5/10 or 10/20 (see homepokertourney.com), the following can work:

100 red (T5)
100 green (T25)
80 black (T100)
20 purple (T500)

Starting stacks (27 chips each):

10 red + 10 green + 7 black = T1000

Rebuys:

2 purple

That puts 270 chips into play right away. It leaves you with 10 black chips and 20 purple chips. Set aside 10 blacks and 4 purples for coloring up purposes. The remaining 16 purples can be used for 8 rebuys.

Coloring up is not too difficult. You can exchange blacks for greens and use greens to color up the reds. (Or have one player buy up all the reds and then exchange them for blacks from the bank.) Later, you can color off the greens in the same way. You just exchange purples for blacks and use the blacks to color up the greens.

If you are certain you want to have exactly 10 rebuys available, then the set below could work:

100 red (T5)
100 green (T25)
75 black (T100)
25 purple (T500)

With the 10/10/7 stacks, you have 5 blacks and 25 purples left over. Use 5 blacks to color up the reds. Use 5 purples to color up the greens. This leaves you with 20 purples to use for exactly 10 rebuys. That looks like it might work for you.

Lastly, if you think you may need more than 10 rebuys/add-ons, then consider this set:

100 red (T5)
100 green (T25)
70 black (T100)
20 purple (T500)
10 orange (T1000)

That would have 17 rebuys. The coloring up is a bit more convoluted, but still doable. You'd exchange 1 purple for 5 blacks, then exchange those for greens as necessary to color off the reds. Later you'd exchange 5 purples for 25 blacks, and use those to color off the greens. [The remaining 14 purples = 7 rebuys and 10 orange = 10 rebuys.]

The starting stacks of 10/10/7 may be a little better than the 8/8/8 stacks at encouraging action early on.
