Jordan Tourism Coalition

We have made our flight arrangements and first and booked first and last night hotels in Amman. We have been e-mailing Jordan Tourism Coalition to make arrangements for a custom tour. They have presented us with a package we like, and have been very responsive. Before we book, has anyone used this company before? I chose it because I really liked their website and they are recommended, along with many others, by visitjordan.com. Did not find them mentioned in Lonely Planet's new Jordan book, however, Any help would be greatly appreciated.
