What's the most cost effective way to launch my website?

Hi All,

This is my first post here so bare with me. I figured this forum is a good place to ask for help since you guys are involved in web design/online marketing/online revenue. I know nothing about such things.

I'm going to launch a website this August for a project I've been working on for some time. I won't say what yet on a public post but its all content/articles based on deep prior experience and knowledge; I'm not selling anything. Just high quality content, about 2-3k words per article. I plan to launch with about 22 articles and maybe add a new one once per month after that. I have a catchy domain name I already bought through GoDaddy.

My plan to monetize the site, since I'm not selling any products/affiliate marketing, is through ad revenue (I know I won't get rich doing this, but if I can make $500-1000 per month eventually I'll be happy).

So my questions are:

Who/How/When do I hire someone to build my site? What costs am I looking at for building the initial site and future maintenance? I want it to look clean and good, like modern high quality content sites I've seen that have fancy comments sections at the bottom of each article, the ability to share it on social media, etc.

Should I put up ads to start at the launch, or should I wait to see my traffic level after some time, and then plan how to monetize it effectively?

Thanks guys!!
