Electric guitar or bass for charity (Salford M7)

Hi.
I'm looking for somebody willing to donate an inexpensive electric guitar or bass which I could renovate/personalise and then donate to the charity. It's the polish charity called "Wielka Orkiestra świątecznej pomocy". They have been collecting money to fund equipment for the children hospitals in Poland for the past 33years.
I'm a bass player at one of the Manchester rock bands and will be playing a concert for "WOSP" in January 2027.
The instrument I'm hoping to get will be put on auction during the concert and the money raised will be fully donated to the charity.

Please let me know if you got any unneeded electric guitars or basses and I'll happily collect them from you .

Kind regards Julian
P.S. the person in the picture is not me. It is Mr Jurek Ofsiak, the founder of the charity.
