What will I need to make my site happen? How much $ for modules?

[Nick_Djinn]

Thank you for your help....Also, feel free to move this if its not in the right place.

Im coming from Zencart, but the fact that its such a pain to have multiple stock photos....you have to rename your photos alpha numerically and use a FTP client to install to the directory.....Are you serious?! So, besides the cumbersome and bloated control panel, this really broke the camels back.

Here are my needs.....can anybody tell me what the costs might be or what modules, paid or third party, I might need to make my site happen? My web design is on a trade basis.

First of all, I like THESE styles....Its a body jewelry business, and we also carry Bali-craft jewelry and gemstones.....Burning Man type styles.

This one is also kind of cool with the hovering.

Also I need the following.

1.Accept Paypal, Alertpay, and Google Checkout.
2. Stock quantity per attribute combination
3. Have links to categories, so people can search by size or category, or both, and for items to fit in more than one category at the same time.

4.....uhhh....I think thats it. My needs are simple. I kind of like that 3d carousel, and I wouldnt mind a mobile version if its not too costly.

I am always interested in the free alternative, unless the paid is far superior.

This is my current shop on etsy.
