Website Hosting

my website http://www.somosguatemala.com is going really slow. My web host which is a shared host, is Ipage. This is how my page is loading http://tools.pingdom.com/?url=www.somosguatemala.com&treeview=0&column=objectID&order=1&type=0&save=true

i was thinking of using a vps like this one:http://dreamhost.com/servers/vps/ the 300mb of ram plan would that make my website quicker?

[No bumping, thank you. If it’s that urgent, hire someone.]
