Adding checkout to website?

I like opencart and have used it frequently. You could link the product page on your website to the product page on your opencart installation. Typically, unless you have experience coding, you don't integrate your cart into the main site like that. You could set up your entire site in Opencart but you'd lose your existing sites work. When I need a shopping cart, I set up the entire website within opencart, so when the visitor comes to the site, they're in the cart software already. When I've needed to keep them separate, I'll link to the shopping cart so they can add the product to their cart and then either provide a button to go back to the main site or set up a redirect. I find this counter productive though, as the goal of the site is to sell products and I don't want potential customer going between what effectively is two sites to do so. I've found it more fruitful to have the whole cart as the site and be able to sell products from the main page.

In your case, with so few products and limited coding experience, I would recommend Google Checkout. It's very easy to integrate it into a website (in fact it has a wizard that generates the code for you and all you have to do is copy/paste. Paypal would also be a good option.

Best e-commerce software is Ultimate Web Builder. It has a lot of features, including payments and inventory management. It also comes with a built-in SEO tool to build traffic to your website..

You could use paypals add to cart buttons if you just want to add it to your existing website. They provide cut and paste code that you can add which will create add to cart buttons for your website. It would be difficult to manage if you added many more items but at only 10 items you should be ok and this will be fairly low cost. Once your traffic starts picking up you might want to look at one of the larger paid ecommerce software tools as they will make managing your site and your store much easier and you can have a more professional look and feel.

Hi.. The best way is to hire a freelancer. I am PHP developer and I can do it for you. Having a shopping cart software such as opencart or OsCommerce is not enough, but also you need a payment processor to accept money through it and get it in cash. So you need as well PayPal account to accept payment through paypal, or 2checkout. Since you have few products, I would recommend Paypal of course, as it will be like plug n play, and will take few hours to be done. I can do it for you for $70 only, and people will pay you using paypal. Silicon Valley for web development http://www.svwebdev.com/
