Boarder Collie 2 years old Male

Here I have my 2 year old short haired boarder collie. He is called Prince and he has quite the personality. He will throw his ball at you to throw it plenty! I haven't got the time for him at all due to working 50 hours a week and my kids being older now they've stopped bothering with him so he isn't even being walked and I feel for him. He's quite happy running around the garden as I give him free reign. So his walking may need a bit of training. But he just needs a harness and a bit of patience. Honestly he's so loving and loyal. He loves cuddles and strokes and will try give you cuddles himself if you give him the attention. He really is a sweet and funny dog. His vaccination course has ran out now. He has only ever been with kids over 7 and he would allow that 7 year old to run and chase him and he would take it as a game. He will bark at other dogs. But whenever he's done that when I've took him out I let him go over to the dog so he stops barking at it as he's just mouthing off.
I cant drop him off unless you're local to me (m3) as I don't drive.
I'm only listing him low as I want a family to be able to afford him but also aware he needs needles again so I'm not selling him for much.
I am editing this to save these questions.
I have no clue how he is with cats as I've never had one and he's never been around one.
Children, I'm unsure about as I don't think for a second he would ever hurt one or even appear that way but I just don't know as he's not really had time with smaller children. More 7 upwards .
Also I cannot lower price to accommodate anyones travel expenses. I already have him on low enough I think.
Don't mean for any of them last bits to sound passive aggressive I just can't keep finding the time to respond to the same questions.
Thank you
