Since you are just beginning off, please consider the following.
Will you be able to expend time on marketing and popularising the website to attract visitors and people towards it? Do you have the skills required for it?
You need an eye catching yet relevant design to keep people on the website once they have come to it. Can you do this?
Would you be able to write the relevant contents and that too in a way which would help boost your rankings on the search engines?
Would you be able to devote time on an everyday basis or atleast as regularly as possible so as to keep the site alive for years to come?
Think of all this. Then comes the money part of it. How much would you be able to invest in the website, its making, its publicity and marketing?
Once you have been able to derive answers for all of this, your website has been done and ready to go live, you would be able to think of 'making money'
Not trying to discourage you at all, just trying to put forth the things you would have to take into measure. Best of luck!
