Fix Some OsCommerce Problems ($30 only)

Here is the work I need done: SITE ONE: 1. Text messaging (via email) is working correctly, but system emails (including order notification) do not seem to be working at all. 2. Add USPS Shipping Method for US orders -- I tried configuring it, but it doesn't seem to be working. Someone who has done this before could probably have this fixed in no time. SITE TWO: 1. Orders are processing correctly, but the invoice on the backend has each item listed twice. Last person who looked at this fixed the 1 invoice that had this issue, but not the actual problem. Should be easy to find and fix. SITE THREE: 1. Fix a CSS problem with the product listing images. That's it! Willing to pay $30, but no more. If you're available to start, please bid and let's begin! :)
