Titan Help!

I've recently come into quite a bit of money and as such, have decided to buy a titan.

I'm thinking a Reaver Titan (or even the upcoming chaos one *drool....*). Now i know I said a while back that i was gonna build my own Warlord. That's still in the works/ design process, but i thought getting a Reaver too would
a) be very, very cool, and b) give me something to refer to when i build the big 'un

Huge problem is that i've never worked with resin before. Ever. Never even ordered anything from forgeworld, therefore, i'm asking everyone if they've got any hints or tips to help me out. Is a titan a bit too ambitious to start on resin with?

Also, any reference material anyone could send me regarding Warlord Titans would be much appreciated.

Thanks in advance
