please give your kind advice.
You just can’t do with this blogspot. You need to run separate scripts for this.
I agree. Why not host your own blog and use blog platforms? It is very helpful. You also have the capabilities of creating scripts and many of these scripts are ready to install. 
Facebook contests really works if done properly.
Well by investing that amount of money you can buy facebook likes at microworkers.
ya…microworkers is good but rsther shift to a good host before that.
