I need a PHP codeigniter expert

General information for the website: Online auction website
Description of requirements/features: Hello,

We are looking for a web developer with an expertise in PHP codeigniter in order to solve the following issues on our online auction website.

1) PHP error preventing the auction timer to function and appear on the front end

2) Monthly membership awards not given to members after payment has been taken. This issue only happens when customers pay for their monthly membership but not when they purchase a credit package (first time purchase). So there must be a broken link between the payment processor and the website for the membership payment.

We look forward to receiving reasonable and professional responses from developers who have experience in solving PHP errors.

Since the deadline is Monday 27th November, developers should be available in the week end to work and liaise about their work.
Extra notes: Deadline: Monday 27th, end of day
