A good idea is to split your time between product creation and product marketing / selling. I've seen people doing 1 week of each. That said, if your target market is not easily reachable online / doesn't read blogs / doesn't search on Google, you're in for an uphill battle. Selling door to door may be a solution but it's expensive and not necessarily effective. I'd look into alternative ways to sell your product: does your target buy services from a class of other established companies (eg. They use web agencies to built websites)? If so you can try to get them to do the sales and agree on some revenue sharing / referrals. It's hard to advise more without knowing the specifics, but you'll have to think outside the box. Best of luck! Ps: for the next product you may want to reach out to potential customers before, so that you'll have some market proof and a potential list of leads before investing time building.
