Magento issues

My website is almost complete but there are 3 issues left to be fixed. I am looking for Magento expert to fix them. 1) I have installed extension [login to view URL] My matrixtable shipping rate is at [login to view URL] You can see every states has their own cities, with different shipping rate based on different subtotal. All I need is to make my “City?? field at checkout page become dropdown instead of text field because if customer make spelling mistake of their city at text field, the city couldn’t be detected by my matrix table correctly and therefore the shipping fee couldn’t be calculated. A dropdown cities would solve this issue perfectly. 2) Refer to [login to view URL], after a customer place order at checkout page, with "Bank In- Cash/Check" selected as payment method, he will be directed to the error page. 3) Product upload function on backend html editor is not working, for both product creation and cms pages. These issues should be fixed 5 days after hiring.
