Hello,
Can you share more details about your project since you are not specific at all. Eg information>
How much products do you need in this store (will you set them in or I)
What payment processor do you want to use?
Do you want to use shipping option calculation with some courier service (usps, ups, fedex, dhl)
...
Based on your description I can install and setup an e-commerce component, with modules, paypal and shipping option.
If you have any questions feel free to contact me.
Best Regards,
Bojan
