Click to Call Me (Using Tropo)

Good morning, I'm looking for a code able to code a simple "Click to Call me", using Tropo libraries. The idea is simple: - The user clicks to open a modal window that allows to enter the name, telephone and email. - The fields will be saved for future reference in a MySQL DB. - When click to "Call me" it will make a phone call between the user and the company. - A PHP file will contain the info: tropo api details, company's phone, MySQL connections, and all the required functions for the library commented in english. If you are able to do the same using a PBX or Twillio libraries please let me know. When posting your bid please let me know your price, time to complete the project and your portfolio. User without portfolio will be ignored. Thank you
