PHP Developer with API experience

I need help with an expert PHP developer to fix a PHP API software. I"m a technical person, so you can talk to me in technical terms. I know for sure this is not a difficult project, so dont give me insane quotes. This is just API calls and anyone who knows PHP and worked in these API should find this easy. This is a PHP analytics tool written in php and api calls like google api and sem rush api. There are some bugs in it. 1. Domain age is not visible in the site metrics. code exists, but there is bug in it 2. Site score which is basically some calculations from the retrieved data is not proper 3. Preview images are not displaying correctly 4. Sometime by default organic keywords which are retrieved by API call and are not displayed properly 5. Yahoo and bing index numbers are not visible properly. Code exists may be use a different provider I would like to use some free API for these purpose. You can access the software using this link and generate a report, you will understand what I'm trying to explain here. [login to view URL]
