Paul, send them your card.
If you have to seek them out, then you don't need one. Help you kid get good enough so they come to you.
Also know that these NHL Agent/advisors cast a pretty wide net. One, it costs them nothing to establish a relationship. Two it's competitive so they would rather bring a kid into the fold then lose them to a competitor. Three, they probably need ten kids in the fold to have one or two come out the other end as pro's to make them money.
Point being they are not shy and so if your kid has any reasonable projection to play Pro or even NCAA hockey they will come to you. If they are not, then your kid isn't that good. Doesn't mean he can't get there but seeking them out is pointless.
As a Junior Hockey Coach you don't necessarily need an Advisor but the good ones are worth their paycheck (if you can't do it on your own) but finding the right one is the tough part. I know a bunch that are very easy to deal with and when they call me I know they aren't trying to sell me a bad kid or bad player. I know a bunch that as soon as they call they basically are saying to stay away from the kid because it will be a nightmare to work with.
You are a Junior Coach and you are reading this website?
AHHHHHH... I don't think so buddy.
Junior Hockey Coaches (which I am one) 100% read this nonsense. It is important to understand the youth hockey landscape in certain areas, especially if you don't have a child that plays locally at the age group. Honestly I don't pay much mind to 90% of it but when you see patterns emerge about programs and players then you pay a bit more attention and learn who to keep watching and who to avoid. Not sure about other Coaches but we start watching the 05 Group this year. Not too closely but just guys to write down the names of to monitor. Closer watch to 02 and 03 group but the 04/05 years are important to have a full grasp on for down the road. Don't really care about the stacked 08's yet but do know which programs to avoid!
Stay away from Hockey Concepts. Biggest scammers out there. You have been warned!
Conor Garland, Charlie Coyle or...or....or...
Wait a minute, there are a bunch of New England born players who went the Q route and now are ripping it up in the Coast (ECHL), that $500 per week will go a long way without a college education.
Here's my recommendation...
If they are not a NHL certified agent; don't waste your money.
A real open niche here in the local hockey scene is to forget being an adviser and maybe just open a 'youth sports public relations firm.' You know, the people who push the kids on to teams that have the kids of former NHL players so they can get looks, contact the local hockey press to talk-up a slightly better than average player, make them available for every tournament, get photos of the kid on every website and for every program, get inside the heads of the local junior scouts and teams by telling them the kid wants to play for all of them. . . oh, that's what advisers do. Nevermind.
