Startup Idea: All-in-one Social Media Management Tool

Startup idea to develop a comprehensive social media management software for small businesses. It should offer advanced options for planning, tracking and analytics across multiple social media platforms.

Work as a social media marketing specialist. It's for a small, independent travel company.

The problem I find with many social media planning, tracking and analytic sites is that they lack in some way. Some sites have great planning and poor analytics, etc. Though I don't mind using multiple websites for the time being, it can be annoying when I do my weekly media planning and scheduling.

An ideal solution to this would be making a "real" all-in-one website or tool for this. Something that gives me advance options for scheduling, tracking and analytic tools. No just in one of the aspects.

I would totally pay good money for a software tool like this. Ideally it would be for those with 5 or less social media accounts to keep things simple. I'd pay up to $1000/yr if the options were advanced enough.
