the investment you are telling is not a big amount,if you find it big ,move to some cheap host ,as your site is mostly content based ,you don't need a good host,
morever like someone said earlier keep a deadline and keep learning free marketing techniques to promote your content ,if your content is genuine ,you are bound to be success,but even if you don't get success ,simply don't worry ,many people like me have started their 1st project and fall down with no profits but what you learn is what going to be useful in the long run , if you thinking of getting quick money i don't think its easy to find unless you have a very unique good idea
