Hi

I have never heard of this company but their website is certainly cleaner and better written than the 'scam' sites I have seen. Could they be well-spoken scammers? Sure... it's hard to tell with just a glance.
It does look like they've been around for a long time, which is to their credit.
I did find
some reviews on another site that seem mainly positive.
All in all they look legit, I think you just have to decide if you want to work on someone else's terms. I hope that helps!
