Rehoming Guinea Pigs (Plum)

I’ve been putting this off but I need to rehome 2 sets of Guinea pigs, all males.
They will come with everything needed for them, I have ample supplies.
There is a group of 3 in one enclosure: Gerry, Paul and Karl.
They are about 2 years old.
The other group is 2 in one enclosure: Marshmallow and Caramel.
I believe they are about a year old.
I took the second set in from a family that couldn’t keep them and it’s just been overwhelming.
I’ve had to take on a second job and just don’t have time for the little guys.
They get fed and cared for but I don’t have free time to give them attention/interaction they deserve.
Rehoming fee of $10 per Guinea pig to ensure they go to a good home.
Will come with ample supplies and cage/enclosure.
Must go in groups as they are social creatures and bonded.
