Scrap a value forgotten in the actual web scrapping process [PhantomJS language]

[Script written in phantom js language – I can provide it to you by email] Actually I already use a tool that scraps for me a web page 24/24 7/7. These varying values displayed in live are actually scrapped and stored in database every 10 seconds. Everything is perfectly working but when I made to developp this tool I forgot to ask the developper to scrap a value. Today I am looking for a freelancer that can : 1 - add the scrapping of this forgotten value and store it in my database like for others values already scrapped. 2 – change the actual scrapping time (10 seconds) to every 1 second. Here is an attached pdf to give all technical details to succeed this project easily and fastly. ** Note ** I prefer to work with Freelancers who only work for themselves and their clients. Like that we can communicate all the day and it is also a way for me to be sure that the job is done fastly and carefully. I need scripts to be well documented and commented to explain the logic used. I need the scripts installed on the server to be sent to me by email too. ** Thank you for your comprehension **
