I'd need to post the saddle to you- easy peasy, then its the cost of the recover, and your cost of postage and packing back again.
I live near Uxbridge so post is easier- I occasionally come up town to eg Holborn Circus, that may/may not be suitable. I could trot over to Hernia Hill for a session over there if its a convenient point- although if the weather was crap it'd be a wasted journey as I couldn't ride.
I'm no rush, I'm not too bothered about colour, if red is what you have then red it is, that would fit in with my kit.
Payment would be by cheque or money transfer etc.
Cheers,

PS can you recover my Mother as she's a bit wrinkled now.... :-))
