I'm currently a web developer myself and got to develop a website for a quiet high up business (which I can't mention).
Believe me for every job you will ever get you will have a deadline, you will have co-workers helping you out to develop the product and also there are times where your deadline can be extended since when developing a product you will always encounter some errors and that's to be expected.
When I developed the website I got a several co-workers to work with, a server side programmer, a UX/UI Developer and a content developer who basically replaces the lorem ipsum with real stuff. With help of co-workers you'll be easily able to finish the product within the given deadline and I was able to finish the site 1 week early so we all just messed about in that week. pretty cool My boss brought over his xbox one and we played titanfall beta and I gave them ESO beta keys and played that and even had a crazy LAN party after work
