ebay API connection to magento (inventory & product scraping)

1) STOCK UPDATE

I buy product from power seller from EBAY I dont get theire stock. I dispay theire product on my site but I need to knwo when they desaper from ebay or get relisted my stock need to be updated every 3 hours . I need a dev to connect this Ebay API (trading,getitems) in C#, VB, PHP to my magento DB mySQL. & register the new API with ebay after.(to unlock server calls this is MANDATORY that can be done after a week)

The ebay API scan ebay power seller stock re-listed product I have already existing product form ebay entered manually on my site this product will need to have stock update and the new poduct I will import from ebay too

2) EBAY PRODUCT IMPORT DIRECTLY IN MAGENTO

I need to be connected to an other api that scrap all the ebaay data (price, large picture, text of some field , delivery days etc.. only) and import automaticaly into magento in the right field section ect. Multiple choice of importing way are needed (bult up 3000 products from a vendor in one shoot, by selected categories, by SKU N° from different ebay sites .[login to view URL] etc) image will be relisted in right section with autogenerate N° , some magento extenstion are doing this .

I dont want new development to scrap ebay. the api is already theire I need experience ebay API dev, no new bird. This is not a learning curve job if you have the same types of experience we can talk

This is NOT A PART TIME JOB i dont accept people that are doing this on the side at night or weekend the lead time is 5 days for the stock update the other one can be the week after
