We need a web application developing.
Ill provide server / database etc.
We will export ad data from 3 separate source. In each CSV, we will have all ad data for USA only. We will need a login panel and way to add / remove users. These CSVs need to be uploaded to the software (1 at a time), we can select what countries we want to offer these ads to (up to 200). We then run the software and all the USA data is used to create ads / settings etc for various countries in various languages (translated from certain parts of the USA data using google translate API).
The final CSV we export / download from the software must be 1 CSV per platform with all data in it that we can upload straight back into the original ad source.
I guess should be built in php / mysql
Budget is $250
