Is there a difference between a neoconservative and a neoliberal?

[Gone to Carolina]

Well some of the earliest neoconservatives were actually former communists / those associated with the 'Anti-Stalin' Left, particularly Trotskyism. Who came to favor a more hardline foreign policy to combat the Soviet Union. Neocons don't really have a coherent domestic policy, as a fair amount of important figures, like Scoop Jackson, were domestically progressive. However, a fair amount of neocons were right-wing economically, especially after the movement expanded beyond the initial discontent among hawkish democrats in the 1970s that brought it into existence.

Neoliberalism on the other hand was a reaction to the progressive / social democratic reforms in the Western World, seeking to institute austerity measures, by cutting social programs and privatizing national services.

In short neoliberalism is economically based whilst neoconservatism is generally focused on foreign policy. Though there seems to be significant overlap with neoliberals generally favoring a more 'active' foreign policy, to put it kindly.
