Need a help with e-store script

Could you please help me? (sorry if this is a bit off topic) I am not
technically minded, but I would like to start an online store. What
should I start with? Are there any pitfalls that I should be aware
of? Thank you

Try this - http://www.ecommerce.com/?pg=products. very good impression!

Take a look at the hotscripts link in my sig, just follow the guides with any php / perl scripts and you should be fine
