Canadian Taxes for oscommerce

We are currently switching over our old oscommerce site to creloaded and are in need of a programmer to install/fix our taxes (canadian), shipping and checkout modules, login. We have set a budget range of $30 - $250 and to be honest we are not sure the amount of time is required for our issues listed below to be fixed. If this is not a realistic budget please feel free to bid and list your asking price for our review. We are willing to negotiate and not interested in wasting time, if you plan to have server issues, email issues please do not respond to this project. We are in a time crunch because of some service providers now and need this project to be completed within 4 days. Issues: 1# We have followed the step by step instructions on how to apply canadian taxes to our products, yet still products that we are testing are not showing any taxes at checkout. 2#We will be using flat rates for Canada and the US plus free shipping after $125 before taxes. Taxes need to be applied to the shipping as well 3#Once the customer logs in the template no longer shows product, categories etc instead only the header and footer. Needs to be fixed 4#We need a print and fax button on the checkout page so that customers have the option to "print and fax there order, instead of paying online. 5#On the home page when a featured item has the "BUY NOW" button hit it goes to an error page. 6#Currently the search button is using the quick find "search.php" which only searches the title of the product, we would like to use the advanced search so that it will serach product decription as well. We are in need of these changes immediately. Once the final bid is accepted a maximum of five days will be given to complete. The site is currently live and can be viewed at: [login to view URL]
