Wouldn't hurt to hire a lawyer. Either way, if its your frist you can probably get it reduced to 9 over. No points on your license and no insurance increase. I just got done dealing with my first ticket. I got one for 21 over (76 in a 55) and I got it reduced to 9 over. As far as cost goes, if its mandatory you appear in court (and it probably is) then you're looking at minimum of $100 court costs, no way around that, plus whatever your lawyer charges if you hire one. All in all, its not too difficult to take care of, just kind of expensive.
