Create Sage One API Script in PHP

Hi There, I need a developer to work alongside my existing team to develop a script that will work with the Sage One API and integrate it into our web application. I'm looking to outsource this work as the rest of my team and myself are flat out on the project. It's a relatively small task but we will have more similar work in the future so we it as the first job in a long term relationship. The SageOne API docs can be found at [login to view URL] and code samples at [login to view URL] For now we need a PHP function writing that will make the following calls: - Create A Contact - Update A Contact - List All Purchase Invoices (for a given contact) - Create A Purchase Invoice (for a given contact) Please state in your proposal that you have read the API docs. I need someone who can start right away. Please write 'I can start right away!' at the start of your proposal.
