I'll second the other child comment and wish you good luck.

I'll also tell you to check out overleaf--it does most of this in a browser, so you have the collaborative aspect if you need it.

I've always used sharelatex, but recently overleaf and sharelatex merged. Nevertheless, have a look at sharelatex too - I prefer their UI.

Thanks for the wishes !
