Camera type and technical ability aside, I think an important part about shooting weddings that hasn't really been discussed is whether or not you truly enjoy weddings and want to shoot them.
On your FLICKR account, you have a wide variety - urban, landscape, expressive, family, self, but all of it has basically the same feel. For example, your skateboarding shots are great, as are your landscapes, and all look to be processed the same but the wedding samples you provided look as though 5 or 6 different people shot them. In your FLICKR, I see very good examples of sound composition, Cup of Bokeh, seriously, that is awesome and I love it, but your compositions seem weaker in the wedding samples. I know this is your first wedding and you said you were shooting mostly on the fly but it could be something else too, perhaps lack of interest beyond the technical challenge?
This is just my opinion but I think people expect to feel some type of emotion when looking at wedding photographs, they want to see a story, feel as though they are there. If you can accomplish that, then you can consider yourself a wedding photograph and charge accordingly. After watching your slideshow and viewing your samples, I didn't really feel anything. Sure you had some nice shots in the slideshow that were technically sound and some very pretty ones as well, but there were many that were sub par that never should have been included - by including them, it ruined the mood of the series, almost as though we get excited to see a good one and then let down by a lesser one.
Again, this is my personal opinion but I think someone who wants to be a wedding photographer should truly like weddings and respect the sentiment behind them. They should genuinely want to capture the emotions that are seen on what could be the most important day in a person's life. A wedding photographer should know that while it gets crazy sometimes, they might need to get everyone in line (not literally) for certain shots that a bride will want to have later - they should know the key sentiments to capture, regardless of the chaos going on around them. If you don't truly have all of this in you, then you owe it to the Bride and Groom to respectfully decline and refer them to someone else, after all, you can't re-shoot a wedding.
If your heart and mind are truly in it, then go for it but your samples so far don't suggest that you still have a ways to go. Also, CODB aside, only you can put a value on your art. If a bride sees your work (again, you should have a signature style) and likes your work - she will pay for it whether it is $300 or $3000. What myself and other people here value it at is irrelevant (IMO), it is what a bride wants that matters and what she is willing to spend for it. What you may want to do is start out low while you learn and increase by a certain amount every 3-5 weddings you shoot. Keep in mind that for each client, the photographers who are charging more are probably producing between 800-2000 QUALITY images per 10 hour wedding - if you aren't, then you should remain at a lower rate until you are.
Again, just my opinion.
