MAGENTO- Install and configure \"Simple Google Shopping\" module

We have three magento sites that we are trying to implement the following module: [login to view URL] We have successfully installed the module on one of our sites. However, when we upload the module into our google merchant center account, we get the following error: -- Missing shipping information (180 errors, only affecting Product Search, Search API for Shopping, Shopping) Missing tax information (180 errors, only affecting Product Search, Search API for Shopping, Shopping) Item too big (14 errors) Missing recommended attribute: brand (180 warnings) Missing recommended attribute: google product category (180 warnings) Missing recommended attribute: product type (3 warnings) -- We are seeking an experienced developer to configure the module so that we are not getting these errors or warnings. We also need to configure it so that the data feed automatically is sent over the google merchant center on a ongoing and automatic basis. Once the configuration of the first site is done, we need to have the same module installed and configured on two other sites.
