Jane, our friend in Hornsea goes to the Beverley Music Shop most Wednesdays. I'm sure if You spoke to him, it would be possible for you to drop the banjo there for him on a Saturday and he could collect it when he visits. If the job is straightforward, he may be able to do it on site and leave it for you to collect the following weekend.

Just a thought? Might be worth a phone call to see.
