If you are a repeat client, then they will probably answer your question. They are still in operation. As for providers that work in agencies, I would say a good portion of them only works for them temporarily. They may come back and work for them in the near future. My first choice is to ask the agency itself by clicking the contact us button and stating who you are. In the past, I've written to other agencies with inquiries pertaining to a specific provider, and they always answered my question as long as it is logical. This method also ensures if they provide customer service to their clients.
