Write some Software

I need someone to fix the mistakes the previous Freelancer, Infotech. There are a few errors in my website and quite simple to fix such as, 1. Under the contacts page the messages do not work. I receive a message but with nothing in it. 2. The State in the contact is in India, whereas, I am in Australia 3. Prices need to be added to a couple product Pages need to be consistent. I only have four or five item pages but they need to look the same as opposed to how he has left it 5. I require quality references If you are successful on fixing my problems, I would like an agreement on fixed cost for six months for your services as and when I require pages to be added on product and general maintenance issues, if any and build a solid relationship for the future. Payments will only be made after the first three months and then final payment on the sixth month and no upfront payments will be considered.
