How can we show that the limit of the following surface integral is finite?

I have an arbitrary parameterized surface $S(u,v)$ in Cartesian coordinates (with finite area) and the surface passes through origin. There is a very small circular hole of radius $epsilon$ at the origin.
Is there a way to show that the limit of the following surface integral is finite?
$$ displaystyle vec{V} = lim limits_{epsilon to 0} iint_S dfrac{dS}{r^2} hat{r}$$
Here $r$ is the distance between origin and points on our parameterized surface $S(u,v)$. $hat {r}$ is a unit vector from our surface to origin.
