Sometimes we just need patience until the pieces come together.....HOWEVER there is nothing wrong with expressing your feelings & concerns & maybe get a time frame when those pieces are expected to come together. Right now you are kinda dangling at the end of a line waiting for anything to start happening & that is a horrible feeling. Communicating that & them communicating what is going on their end is how trust is built. Sounds like time for some real communication so they also know that you care & are interested in knowing their progress too
