We are planning to build travel portals around 10 new portals. We are looking for developers based in Russia, Thailand, Vietnam etc who can provide end to end technology solution. We are currently getting raw data in excel format from our provider also they have XML web services. We are open for both the ways. It's one time development which includes creating database using the data files and pull the data from the database and generate pages. Also please mention if you have any specific experience of travel portal integration.
