PHP Laravel Web script Modification

I have a PHP script and I need some changes to it. You must need to have a Ubuntu VPS to work. All changes must be done in that server after I've accepted the offer. I can't tell you the changes prior to the acceptance of the offer due to security reasons. You must have a good knowledge in PHP and LAMP to finish this work. So if you're experienced in these technologies send me a message. I will attach the documentation and After You send a message I will send the script files. After the payment, You will have to migrate the modified script to my server. Thank you!
