What's a good way to earn money with Computer Science?

[fredreload]

Alright, before you consider this as an ad, it is not. Throughout the years I took computer courses and see various computer programs let it be graphics, algorithms, recommendations, Youtube, Google, search engines. I want to know how to earn money with it aside from the standard I take a contract and design a web page for the contractor or company. I want to create something that would allow me to earn money, let it be data analysis or graphics. Anyone knows any idea how computer programs can be used to earn money? I'm not saying doing it in an illegal way but something that gathers a little bit of money like a cent or two a day. A search engine maybe? The next Facebook? Any ideas would be cool

That depends whether you want to concentrate on enterprise clients, or private clients.

Private clients pay immediately, prior receiving software, relatively small amount of money. So there is needed plentiful of them each month.

Enterprise clients pay after delay (could be even 90 days, see VAT tax pay delays), when job is done, if it's contracted job, so there is risk you work for nothing if client won't pay ever.

Each client will pay much more than private clients. But often it's single time job, that cannot be reused, or resold to multiple clients.

Large contract which is not paid (f.e. client bankrupt after receiving it, but didn't pay), could end up in your's company bankruptcy.

Because you have to pay VAT tax to government from money that you never saw on eye.

Say contract is 1 mln euro, VAT is f.e. 22%, so it's 220,000 euros to pay to government.

You should take advance payment and/or split payment to couple smaller chunks while project is progressing (especially modular structure of app).

Write a cheat for Pokemon Go. Technically legal. Lots of potential customers. Caveat: The idea is not the prime example of a unique idea that no one else will think of, and you may be too late to jump on the bandwagon.

 

Seriously: If anyone with good coding skills had the idea what the next Facebook is they would probably pull it off themselves instead of posting it in a forum.
