Hi, i have read your project description, and i basically understand what you need. However to give you precise budget and schedule estimate, i will need more detailed information. However i'm professional web developer and administrator, i have plenty of experience with Wordpress custom plug-ins development, and various 3rd party API implementation, so i'm fully qualified to finish this project quickly and to your full satisfaction. Please provide me with more information (especially what features of the API you need), and link to the API documentation by private message, and i will give you exact budget and schedule. Kind regards, Josef
