Hi Sam, i am sure you can appreciate it is very hard for me to provide a accurate quote without seeing the dent first. If you can send a few digital photo's to info@pdrtek.com.au i can have a look, or have a look at my website here at www.pdrtek.com.au or just give me a call to arrange a time and i can come out and supply a quote. As a very rough guide dents the size of a 5 cent coin will start at $60 for SAU members, if you have a few dents on the same panel then i will discount to do a few dents on the same panel.
Hope this helps.
Cheers
John
