Should a website cost $2,000 to build?

That's a big investment just for testing the waters, I recall someone here reporting setting up a tshirt shop with original designs and a shiny new site costing $1000 who was still waiting to make his first sale.
Wordpress is not a great platform for online stores, some payment processing services won't allow it because of the security holes. It's fine for putting a simple catalog online yourself, perhaps including original articles to help gain search engine ranking.
Consider first selling through a marketplace like Ebay or Amazon, which have ready made customers as a simpler way to gain some experience, there are also dedicated ecommerce site hosts with shopping carts and payment processing built in, which might cost $20 - $50 month.
Ultimately you ma find getting prospects to the site to be a bigger challenge than setting up the site, free search engine traffic is more difficult for sales sites that don't have valuable content in the search engines' eyes. Paid advertising may be needed to scale up sales volume.
