There are definitely some "red flags" to make you leary !
You would think if it was legitimate they would at least:
Give the actual name of the business so you could check it out for complaints
Have a business toll-free phone number, not just an email, which doesn't even look like an official business email address ending with the business name after the "@"
Have an actual business web site "www.(name of the business) .com
…...I just did a search engine search for that email and only saw related results for the same message being posted on 2 other detecting sites.
The mods could likely use the person's IP address and see the source -

In all fairness to the OP, if you are indeed legitimate, please post the actual business name, business phone number, and business web site, I mean really, put yourself in our shoes, wouldn't you be leary if an offer was so vague without any verifiable info for you to verify ?
