Did you try googling her name - Preethi Gnanasundram? Lots of info came up.  Also, check with Abstractorwatchdog.com to see if there is info on this company and/ or this person. Better yet, call her to get the info that you need such as a mailing address, phone number, fax, etc. Ask for credentials! If you don't feel confident that you will get paid, either put the company on a tight leash with a line of credit ($500 or so) or just do not accept the work. Unfortunately, we live in uneasy times accepting orders from new clients so it is always a gamble. Good luck!
