Is wordpress reliable enough and could it be used with a proper plugin as a medium sized ecommerce site? We are talking around 1500 products here, estimates say around 5 to 10 costumers per day, usually returning ones. Some days none.

I have a client who wants to sell online. We are situated in a country where people dont see web as something serious enough. Still, they literally have a budget of pretty much none. And 1500 products to sell online.

Magento, or any other open source ecommerce platform are out of the question, there is just no resources for starting something like that. Or any time. Only way is something free, small, absolutely not resource hungry as Wordpress.

I have to fight with making it work with only what i have at disposal. Also, if you can recommend any wordpress plugin for the job(WP-ecommerce?), i will be very thankful. I guess something paid, up to maximum 50$ would work too.
