3 eCommerce site design in one platform

Hi There, 1) Free but Robust Platform - No License Fee Required 2) One Inventory System for Multiple Domains - (as .com/.[login to view URL]) all site with single point Product Image/ Name/ Price/ Size/ Colour updating [login to view URL] would save our time. There will be language section in every website also. 3) We need the ability to deactivate and activate any site/ product from one Admin Panel. 4) We can put different promotion if different site in different time. 5) Since we have many colours of same product and we keep on adding many colours there should be no limit to which we can add several colours in the same product. 6) Zooming in products should be possible and surfers can just click on the image to get transferred to next image in the list of images. 7) Blogging features with site 8) Possibility of changing templates from time to time as and when required should be possible. 9) As mentioned to you I take photographs of my products myself but I am unable to get the time to photoshop them myself. I would require the photoshop to be done for at least 100 photos to complete the design at your end. 10) There need a secure developing so when we upload any image or writeup from any computer ( which may be infected) the website is not infected. 11) SSL integrated 12) Signup facility for customers so that newletters can be sent when new product launch and they do not have to fill up forms again if they make a new purchase online from our sites. 13) I have some reference sites after getting reply from you, I'll send you more information. 14) Design should be done SEO friendly and W3C validate. 15) There require three different currencies to mention in three different domains for the same product. Before bid this project, please read the whole project and let me watch your previous completed projects. If anyone can complete this project properly I can provide you more in future.
