You have to be very creative in the kitchen so that you don't miss out on making this tasty meal. You can cook a beef stroganoff in the crock pot on a low budget by using a cheaper cut such as chuck roast. This cut of meat will be tougher than the more expensive ones but you can easily work around the problem by increasing the cooking time slightly and browning the meat well before you add the sour cream. You can even pressure cook the meat in a bit of broth before you add the sour cream. The resultant meal will be delicious and tender. Pressure cooking the meat will also help you use less cooking fuel. You could also reduce the amount of meat and increase the amount of mushrooms in order to reduce the cost.

First and foremost, know your ingredients. There's a saying going around that says "if you don't know your meat, know your butcher." If you're unsure about quality, freshness anything at all, ask someone who knows. Any butcher or purveyor worth their salt will be more than happy to answer all your questions and make possible suggestions to alternatives, depending on what your recipe is. The cooking technique is just as important as the cut of meat you may be using. For instance, you're not going to want to pay top dollar for a Beef Tenderloin, only to make beef stew in your crock pot. Knowing primary and secondary cuts and what type of cooking technique their best for saves time, and often yields a more flavorful dish.
While having catering provided, with service for 2 hours...do keep in mind that guests will become hungry again later in the night. Easy to make food that is filling is great to serve once guests have had an intake of alcohol.
