Embedded PhP, MySQL site needs a few display issues fixed.

Qualifications of developer: ====================== You need to be able to work on an existing code base in PhP, MySQL, and Linux. You need to have advanced knowledge of PhP and ability to work with existing code base without causing regression in other areas. You should know how to setup cron jobs. Project: ====== There are a few issues that need to be fixed. Code already exists and the issues are regression. Completing the project should not take more than two weeks since there is minimum new code or functionality is needed. 1. When new banner for the site is loaded, duplicate banners are seen in ADMIN panel under "Manager banners". This does not impact the display of banners. This is a regression so bug needs to be fixed. 2. In ADMIN panel, new banners can be loaded and assign to different countries. Loading banner works ok but ADMIN should be able to have the option to assign the banner to all countries. 3. The site has certain ads called ADMIN ads. These ads are displayed in most of the pages on the bottom of the page but not all pages. ADMIN ads should be displayed in all pages. Currently when PAID or FREE ads detailed page is opened up, ADMIN ads are not displayed. 4. The site has ads called classified ads. When detailed page for classified ads is opened up, 3rd row should display other free classified ads. If there are no free ads for the same category, then display free classified ads in other categories. The purpose is we don't want to have a empty ad display if there are no ads for that specific type. 5. When user defined FREE ads, if price of item is 0, program asks if item is free. PAID ads needs to work the same way. 6. There are some entries in the SQL database that needs to be removed. Project notes: =========== 1. After the above items are completed, the new code needs to be pushed to the live site. There are other new code that is working and that new code also needs to be pushed to the live site. 2. The code on the live server needs to be copied to our backup site. After code is copied to the back site, it needs to be working ok including all the cron jobs. 3. Completion time of the project is very important. You need to commit to completion of the project in two weeks. Payment will be done after completion of the project.
