Insert, delete and output data for database project

I am looking for someone who are experts with PHP and database. I need some help with complete the project by doing those: 1) I want you to work on my script [login to view URL] to open each url to allow me to store the full information in a database without any data is missing. I have got a problem with insert the data into the database as there is an error "[22-Jul-2017 18:50:56 UTC] PHP Fatal error: Call to a member function exec() on a non-object in /home/chris0147/public_html/test_mydatabase/[login to view URL] on line 153". I want you to have a look to find out what the problem is and fix the issue. 2) I want you to check on the programme stop_date format for each channel to see if the programme have finished it as I want to delete the data from the database when the time have passed, example: In BBC One program "BBC News at Ten" it have finished at 10:30pm as my current time show at 10:42pm so you delete the data and check the next data for each channel. 3) Then the next thing I would like you to do is to work on [login to view URL] script. When you click on the [login to view URL] url for each channel, I would like to find the channel from [login to view URL] to get the channel and the programme information to extract the channel, start_date, stop_date, programme time and description to output them in get-listing.php. If you can do it for $50 that would be great. You must have your own server and you must have teamviewer to show me the proof that the work have been working on and complete it. Thanks for your interest.
