Can someone inthe UK make me a seat?

Hi all,

I have recently bought my first ever classic bike, and have embarked on my first ever restorations/customisation.

One of the things totally out of my skill set is making a seat - I want one the full length of the bike, but brat style - so think and small.

Any one know how I might go about this? See photo of my work thus far and the dreadful seat I put together as a temp option



Cheers!
