Yep, any good vinyl sign maker should be able to replicate what you have. It WILL be a bit pricey, but i dont think it would be $1300 pricey. I have a friend of mine here in ATL that i use for all my vinyl work, and he can replicate anything i want.
Just be prepared for them to give you an "installed" price, THAT may come close to the big number above, but if you've never installed HUGE vinyl stickers, trust me, its worth it to pay someone that has. Ive done it, but i messed up quite a bit of vinyl during the learning curve.
