So i’m looking to create essentially a website, that will be used to host tournaments. Things to come with it like, users, loging in, being able to purchase credits within the website, and have them use said credits, towards tournaments and other misc things.
Guess that’s the broad question without going into too much crazy detail, i’m sure by reading that most of you will be able to point me in the right direction 
Thanks
for front-end, you have html & css (structure, design and layout of website) and JS
on the back-end, there are dozen of options. PHP, Python, Ruby, Java, Golang too name a few, and you need a database, which again, there are multiple options (mysql, mongodb, postgresql too name a few). You will certainly need to learn some SQL which databases use
how long, do you think it would learn to do such a thing? Would it be worth putting the time in, or would it be better to out source it while I learn?
That will take a while, even to make a raw version i think you will need easily 6 to 12 months.
but its certainly a good learning process.
