I can suggest the following, for maximum sales results...
Take time to create a user friendly website. You do not need to know how to code, there are plenty of drag and drop site creation websites available. You will need to setup a merchant account to accept credit cards. You can even do this via PayPal.
Be sure to purchase a website marketing book to help you with the best ways to market your new website. (ie. Internet Marketing 101 : Strategies from a Yound Web Marketing Guru by Neil Mirchandani ) There are millions of websites out there, you have to work hard to make yours visible amongst the rest. At first it seems daunting, but the hard work will surely payoff in the end, this i know first hand and can attest to.
You should also use Ebay as a marketing tool. Pay the $20 for the featured plus listing for your product. This will bring a ton of exposure to your ad, around 10 X more ppl will visit over a regular ebay ad (probably more). In your ebay ad, have a catchy phrase to entice the buyer to click on a link which will take them to your MYEBAY page (only legal link allowed in any ebay ad - can not directly link to your website). Then, at the TOP of your MYEBAY page, have a clear link to your webiste. This is a great way to advertise your website, along with the other methods explained in any website marketing book.
After about 6 months, you should really see higher sales, a better page ranking for your website and more profit.
Realize, any business will take time, research, dedication and patience above all. Take it slow and you will succeed. Rush, and you can invest too much, too soon - and lose it all.
Hope this helps.
