Hiring someone to configure my shipping settings/options

It confuses me all to hell and I dont understand it =) Heres what im looking to do:

Charge actual shipping costs (USPS, UPS, FedEx)

Set shipping to free for purchases over $25 to the US/Canada

Exclude certain items from the free shipping over $25 option

I am located in the US.

Please send me a PM if this is something you have alot of knowledge about and how much you are asking. I will need this done this week. Thanks!

After hours and hours, I think I figured this out.
