Data exchange between local Mysql and Ebay

Hello, we need php scripts for 1. storing all ebay transactions from different Ebay account in one Mysql Table (in an intervall of about 5 min). (Chronjob can be used)(token from Ebay developer should are stored in a mysql table) 2. Upload offers to different Ebay accounts. All data are stored in a mysql database. In an intervall of about 5min the script should upload all offers which are marked for upload to different Ebay accounts. If there will be problems the article should be marked something like failure and the reason should be stored in a table. All uploaded article should be marked something like "uploaded". A history table ore something like this would be fine. 3. Deleting ebay offers from different Ebay account when a article is not in our stocklist anymore. Stocklist is a mysql table. The association can be made with our article numbers and the Ebay Stocknumber. Please notice that Article in our stocklist can have different quantity and Ebay offers can have more than one stocknumber. so lets asume article nr. 10, nr.20 and nr.30 are allmost the same articel: used HP Printer LJ 2015. nr. 10 has 10.000 pages printed, nr. 20 has 12.000 pages printed and nr. 30 has 14.000 pages printed. The ebay article is one article with quantity 3 and the headline will be something like used HP printer under 15.000 pages printed. The ebay stocknumber will look like: 10, 20, 30 (or 10 20 30). as soon as nr. 30 is deleted for some reason from our stocklist quantity of the ebay offer should change to 2 and stocknumber should change to 10, 20. I have done some similar thing and can explain how I solved it. 4. redirect customer to our Website for add aditional information and to check shipping address and stuff (like it is in afterbuy) no webdesign needed. Thanks for your bits.
