MONEY
You will not make money with that traffic, it is not even worth trying. Your site is in an undesirable category. With maximum advertising (popups, banners, searchboxes etc.) you can make at best US$0.003 per visitor. 54 uniques in a month will make you about .15 cents per month.
Web publishing is a tough business and you won't make fast money. The question you should be asking yourself is am I willing to spend hundreds of hours to make a few extra dollars when I can certainly make more money doing anything other than web publishing.
If for some reason you insist on being a publisher. You need to publish something. Look at it as if you were putting out an interactive magazine about your topic. Your site will need original content a reason for people to come back. It is hard to get visitors. So you want to make them loyal. You can go to DMOZ.org and download their directory of your category for free that will help.
Learn SEO, without you are dead. I have friends with sites like yours who are good at SEO and are making a few thousand dollars per month. You can start learning SEO by going to Searchengineworld.com and reading everything on the site.
Before you even think about a sponsor get your site to at least 1000 uniques a day. I see that you are good in PHP download a free toplist script like PHP topsites or listsitepro and install in on your server. Do a search on google for topsite lists about your topic and join every single one. Send them 1 click each yourself just to get on the list and that should give you a base of daily traffic to grow.
After you have something worthwhile to promote and sell ad space on, you set a goal of making $1 per day. For a site like yours you should be able to do it easily with 500 to 1,000 uniques per day depending on how much advertising you want to dump on your visitors. When you get to $1 set the next goal at $5 and keep increasing it.
