Has anyone else faced this problem as a beginner?

​

I live in a country with a very small market, so as a beginner—no matter how good I am—I can’t realistically expect to write a high-budget film because no one would be able to produce it. Or maybe they could, but not for a beginner. I have no choice but to write a low-budget film, at least to build up my reputation. Has anyone been in the same situation? It’s pretty hard for me to move the plot forward if the movie always takes place in the same location and still keep it interesting. What do you recommend?
