Nice layout. Personally, I'd tidy the edges of the I and V, remove the curve from the cross-stroke on the 4 and have it meet the right hand ear/serif of the 4. That's just me and my design eyes talking. It's your logo so it only matters if you're happy with it
However, if you wanted me to knock up what I'm talking about then I would gladly do it. Off work with manflu so I could squeeze it in in-between dying and using more tissue than a teenager who just discovered porn.
