Title: Hi Guys, 
        I am long time HN follower. I always been benefited from HN community.<p>I am a full time developer and can code in ASP.NET (both web form and MVC), PHP (also i am beginner in ruby).<p>I want to build web app from which i can earn $200 - $400 per month.<p>Its not a big amount but it gives me following benefit which is more valuable for me.<p>1. Motivation for bigger move.
2. Getting experience in running SaaS based apps.
3. Side income.
4. Good learning about business, marketing and other non programming things.<p>I know i can make these kind of money though some freelancing but that option i am not looking for now.<p>I can invest my time 2-3 hours on weekdays and 5-6 hours on weekends (around 20 hours in week).
Also i can invest up too $300 if i have to do buy some sort of services/hardware etc.<p>Problem is I am not been able to think about any web app idea which solves some problem. 
Please give me some idea about any web app which I should build.<p>I am not from US or Europa.<p>I am having high hopes from HN community.<p>Thanks in advance.
