Very nice job and some suggestions,
1-submenus and fonts should be some bigger.
2-as cpoalmighty said bigger Logo.
3-distance between menus and submenus some lower!it mean a narrow menu bar.
5- you can place domain chekcer instead of about us un home page under slider,in blue area.
6-place accepted payment types in footer.
7- also in vps plan your vps configuration is 500Mb Ram.normally it should be 512mb
