Possible sear spring wear on my p53

[itsatrap]

Hello, I am reasonably certain that my sear spring is worn out, because my p53 Enfield is engaging the trigger on half cock i.e I can fire at half cock. My question is does anyone know of a competent gunsmith that could help me fix my problem. I am located in Montgomery County, my first thought was the regimental quarter master in Gettysburg might be able to help, but if I could help it id like to use some one closer. Thanks. Upon further inspection I think the tumbler has uneven wear on one of the edges.
