Yes of course,
The whole competition is basically a marketing exercise for sites to promote their own offering. One of the requirements of the channel for all participating sites was that they have at least 2 professionals and preferably 3 out of the 6 that make the heat with the remainder being internet qualifiers.
The majority (if not all) of the pros in this event have been by invitation only and they have all had their buy in paid for by the sites (again this is to the best of my knowledge, there may be the odd one that has bought in).
