If you're waiting around for that breathtaking website to be complete or for the product to be perfect, you won't be getting anywhere fast. It's 2018 already, and it's time to take action.
First, you should test your idea on a sample audience. Ask people for feedback and try to ask people who will actually be customers. Your mom can only buy so much product from you before you need new customers. Testing your idea is as simple as asking, "Hey would you use this? What would you pay for it?" Then take that feedback and use it to guide your further product development and your marketing strategy. In a makerspace like this, it's also easy to ask the other makers around you for feedback and even for advice on design, packaging, pricing, etc. It helps to be around others who get what you're doing.
The next stage is to make your product good enough to sell. Improvements can always come along the way. Apple has been doing this for years. Give customers what you have now, and when improvements come, you can sell those too. For example, when I started making jewelry, I had some great design ideas but was limited to only using polymer clay, so I did that until I had access to a kiln and upgraded my material to porcelain. The first designs sold well because people liked the way they looked, and the second version still sold well because there was great design and a more durable product.
The other thing that will help you sell your product is by having attractive branding, packaging and marketing. Every decision you make from the company name to the logo colors, the fonts, and even the box you put it in all convey some message about you and your company that either make people want to be part of that story or barely notice it all. You want to be noticed. Look at some recognizable brands or other popular handmade brands to get ideas on how to do this well.
Then, once you have a product you know people will want, and you've packaged it well so it tells your story for you, you need to get it out there. You can start an Etsy page (but it's grown very competitive), you can sell at shows (just make sure you find good ones), you can give some product to "influencers" to help get the word out about your item, but you must build some sort of online social presence, be that Facebook, Instagram, or Twitter.
If you can grow your own following, you can have an audience and customers anytime you need. If not, you'll be relying on luck or spending lots of money on advertising dollars.
So don't let 2018 pass you by. Start networking with other makers at one of our coworking days. Hone your skills and get your product to a sellable state, making prototypes. You can use tools at a makerspace like ours for a low cost. Get your company basics prepared to share, and get on social media.
Some good resources for design and web building are Canva.com and Weebly.com.
