Suggestion required for Web Development Company

Hello this is Gulshan Negi
I am a software developer. I have a question: when we begin developing any project, including any website, web application or game, we often get confused about where to begin and how to begin, and the entire process takes far too long. I was looking for a web development company who can assist us or help us in web or app development including some new ideas as well as something different things. I don’t know how to do these kinds of things. I need some suggestions on this.
Thanks
