adding google checkout to www.gasmanuals.org.uk

Please note this project is fixed price only. Bidders can speak good English to resolve any communication problems. I am looking for a person that is capable of replacing a PayPal payment on my website to a different form of payment method, maybe Google Checkout if compatible, once installed the payment method should enable customers to download a single pdf link or join as a member to my website which enables them to download as many pdf as they want. The payment method on the website worked with PayPal for a while but has now stopped working, but needs changing over to a new payment method anyway, please read the following and fully understand what is needed before you bid and visit my website to fully understand what is needed to ensure he payment method works. It was set up with Google checkout in Sandbox once and tested to be working fine but for some reason would not work on the live site. Before the bid is awarded the freelancer must inspect the internal workings of the website to ensure they are capable of completing the project and the bidder must explain what they intend to do to resolve the issue, no money will be paid until you can confirm this. Project description: Customers must receive an email link with a download single pdf to my website after payment has cleared. Also a customer option to join as a member and log on to have full access to all pdf downloads on my website. (This facility has already been installed in the website software using Pay Pal and needs changing to a new payment format, but needs testing to ensure all works ok). Web address: [login to view URL] Once new payment method has been completed please prove that both payment methods work. Also annual membership payments must be processed as above and joining details and dates must be registered in the installed hidden webpage software to enable me to delete the membership once the membership has expired. This is already built into the website hidden software and works already with PayPal, it just needs changing over to the new payment method so should not be too difficult to change. A 30 day after sales error repair must be included to resolve any errors in the bidders work. Milestone payments must be agreed at start of project, on completion of project and after the 30 day after sales service. 3 Milestone payments will be made in total, the first being paid to the freelancer once they have explained what they intend to do to ensure all newly installed payment methods work. Any changes to the website to help the payment method work easy can be discussed but will be done within the price and if it does not work the freelancer will repair the error at their own cost. SKYPE contact would be needed to discuss updates.
