I was offered a job with, "Electronic International Shipper incorporated" and wanted to know if it is a legitimate company.

Did you specifically apply for the a job at that company?

Yes, this is a scam. I received the same email. Just googled and found your question as well as another person who followed the trail to the scam. Apparently, they send you money orders to be cashed. You are to keep 10% and send the rest on to the scammers. The checks bounce and you are out all the money you sent them.
