Chips distribution help.

I need some advice on chips distribution for a home tourney for 7-8 players. im using a custom chips set bought on ebay.
its the standard chips distribution for the 500 pcs. set. 150 ($1), 150 Red ($5), 50 Green ($25), 100 Blue ($50), 50 Black ($100)

So what is the best distribution with these ? and what about the blinds level ?

thx and have a nice day.
