Slow Down. You are trying to build a skyscraper and you don't even have experience building a dog house. You are not likely to be successful if you try to build a website with a shopping cart for your first website.
I also recommend building a simple one page website, as was suggested by someone else. No shopping cart, just a one page website that you can lead your website visitors to your Etsy shop.
Here is an example of a one page website without a shopping cart that I built for someone a couple of years ago.
http:www.sfth.orgJust because you have a website doesn't mean that anyone will ever find it. You will have to know how to optimize it for the search engines (SEO). If you don't have your website optimized for the search engines your website will not show up on the search results when someone is doing a search for products like yours.
If your website doesn't show up somewhere on the first two pages of the search results chances are pretty slim that anyone will ever visit your website.
If you want to pay someone to design and build a website for you then you will be looking at anywhere from $99 to $500 per web page, depending on what you want to have on your web page.
Also, when someone designs and builds the website for you and you want to update the website you will have to pay them each time that you want to change a photo, change the text or create a new web page. You are probably looking at around $40 to $50 per hour.
I would also recommend having 3 websites instead of combining everything into one website unless the products are all very closely relalted.
Once you have your website online you will then have to market your website. If you don't market your website you will not be getting a lot of visitors. Marketing is something that you will have to do on a regular basis.
