Welcome to Flyertalk!
As you describe the situation, what choice do you have other than to try the visa service. You mentioned you emailed the first one of several, you could contact others to see if you receive a consensus response. Perhaps as you fear, they may all be after the money, but maybe some are more upfront about things.
