USA Demographic Information

I need a database or spreadsheet containing demographic information on US zip codes. All of the information I am requesting can be found either from one of the US census records, or a publicly available zip code database. I need it properly formatted, and indexed by zip code. I have attached a sample spreadsheet highlighting a proposed format. I am open to a similar but different format if you think its superior. I would like information on every zip code regarding the following values: Average Household Income Average Discretionary Income Average Home Value Average Age Political Party Genders Present Average Number of Children (household) Ethnicity I am flexible when it comes to these fields. Please let me know if there are any others you would like to add, and I would be open to a bonus. Conversely, please let me know if you believe 1 or 2 of the above categories will make the process drastically harder, and I would likely be willing to omit them.
