Hi hoquet,
I am a new freelance here. I plan to develop a good reputation here and therefore would be doing this project at this extremely low rate. I have good enough experience with php and MySQL. I have made a number of projects in php and mysql including: [login to view URL] [login to view URL] [login to view URL] and a site similar to [login to view URL] as a college project. Also made a private project for Credit Suisse which was a social networking website especially for students and professors.
From what I follow from your project description, I can fetch the json data from the given link, process the data and use it display google charts. The average can be calculated using javascript programmatically. The 24 hour profits should come from MySQL database. To improve the responsiveness, what I can do is, write an AJAX script to fetch the 24 hour profits from the MySQL database. Other than that, I can use bootstrap to improve the looks of the table. Paging can be easily implemented using javascript and hidden divs.
Thanks for reading the proposal, and hope to get this contract from you. Again, I aim to build a good reputation here and I would be thankful to you if you contribute to my [login to view URL] can Inbox me in case you want to have a personal chat to further discuss the project.
Thanks!
