Looking for Legal Industry Members & Investment Firms for Litigation Financing Article

I’m writing an article on litigation financing — which involves an external third-party that’s unrelated to a lawsuit providing funding for a law firm to work on the case, in exchange for a share of the judgment or settlement — and I’m looking for law firms that have used a litigation financing model in a case, attorneys who have worked on cases in which litigation financing was used, legal industry finance, operations consultants or analysts who can speak about the trend and investment firms or other organizations that have provided funding resources for litigation. The article is for a legal industry publication and will touch on why the financing model is becoming a growing practice within the legal field; how the arrangements are typically structured and other elements involved in litigation financing. If you have a source in mind, please let me know.
