Oh yeah, also here are a few other pointers I forgot to throw into my other post.
Captial- Make sure you have sufficient capital before taking on a venture like this, it will make your process go much more smoothly, also save some money for the unexpected, and advertising.
Advertising- The best advertising is word of mouth. Depending on what type of site you have determines how effective this method will be. If you have a store for example, you may need to resort to more traditional means of advertising, or just have killer sales and promotions
Design- When it comes to designing your site, get it done right. Even if that means spending some extra money. It will save you a lot of time, money, and frustrations down the road. I can tell you this from personal experience.
Failure- Don't be afraid to fail. I've done it, and it happens to the best of us. It's honestly the best way of learning. Even though it's costly and I've wasted hundreds of dollars, it was worth ever sent. I have started two other websites that failed before the current two that I have open. I'm only 17, but I've learned a lot, and I'm getting ready to launch my fifth website.
Good luck with everything bro! And if you ever need anything feel free to ask!
