Attempting to replicate Yards Brawler for wedding

A friend has asked me to make beer for her wedding.  They lived in Philly for a while and became fond of Yards Brewing Brawler.  They asked me to create and English amber and cited this beer as a guideline.  I have tried this beer before, but for the life of me cannot remember anything about it.  Now that I live in Vermont it is impossible for me get a hold of locally.

Therefore, any help with the profile, or even a clone is welcomed.  I’m an all grain brewer.  I have the base malt, but need help with the specialty malts and yeast.  My original thought is this:

85% english base
10% medium caramel
5% of either biscuit or special roast
1 oz of english bittering hop at 60
maybe a small dose of english hop at 5
wyeast ESB yeast

Thanks
