Shared hosting or my own VPS?

I would recommend you to find shared hosting first, but you need to find the reliable one. And then, if you have high traffic later, you can upgrade it to VPS.

A fully managed VPS will be best for you and also just dont stop there and once you got enough resources go for a full fledge dedicated server even a core2duo as you will see a major difference in performance from a VPS to a dedicated server too and a VPS is a very good and important upgrade from a shared hosting

Since, you have multiple sites I would recommend you to opt for a fully managed vps hosting solution. With VPS, you would be able to manage your multiple sites efficiently along with an adequate amount of server resources would be available if a sudden spike strikes you. Also, you get the flexibility to install/uninstall any kind of third party software's and applications. Overall, get a better control over your web hosting server environment.

In your situation I'd go with share hosting which allows multiple domains, or a reseller account which can give generous amounts of disk and bandwidth, allowing you to keep all your accounts in 'separate' containers as such, while still under the one account. Makes it easy for backing up and moving sites if need be.

Reseller accounts don't need to be expensive, though a good host will save you headaches over a VPS.
