Ceramic Bezel Dent i am sad...( Photos included)

[thesmallwave]

Hi guys, i am quite sad after i hit my Rolex against the corner of steel table at work and i've got a little scratch and a small dent, the sharp part is the as much as i can see but is bent inside. The rim that holds the bezel has a small dent, wich is small but doesn't look good as you can see it in the photos.The bent and scratch are under 30.
My questions are:
Shall i send it to Rolex for service?I heard it takes up to 3 months.How much does it cost?
Can the rim be replaced and scratch be polised without need to send it to service.I live in South London, so what can i do?
I am willing to pay up to £ 100,but if is needed that the whole Cercamic bezel to be replaced then i have to live with it as will be very expensive.
I know it was my fault, and the Submariner is very tough watch as i hit it hard, but the glass is ok.
Your help( advice) will be much apreciated.
Many thanks, Levi
