Need 500 SSAT / SHSAT Math Problems

Hi, We're looking for anyone that has good knowledge of the SSAT or SHSAT test and is able to clearly communicate and present math concepts with the help of supporting diagrams. (Here's some sample problems: [login to view URL]) Here's the breakdown of what we need: -500 Math Problems Consistent With Those on the SSAT or ISEE test with explanatory steps on how to do them seperated into different categories (eg. algebra, factoring...etc). 80% of the problems should be word problems and at least 20% should contain a diagram of some sort. Thanks!
