Install and make functional an existing OS Commerce site

I have purchased an OSCommerce template site for selling childrens clothing.? I will have the domain name, web space and MySql db. You will have full access to install.? You will need to test locally before going live. 1.? I require the site to be installed and made functional/operational.? 2.? There? will be an? element of personalisation of the site although I believe that most of the functions I will require are all build into the template - things like - multiple search options (sex, garment type, designer, latest products? etc), garment sizing options, real time stock numbers, 'other purchasers of this product liked this', scalability to use multiple currencies in the future, shipping, discounting, promo code, affiliate options.? You can view a demo of the template here;? <[login to view URL]> I'm not sure what image viewer is included but if it's not good enough I may need a better one installed. Nice bit expanded pix from thumbnails without opening a new window. 3.) There will be up to 300 different (sku's) products to initialy be loaded up. Images/text/prices etc. 4.) So I can manage this myself going forward, I will need a good but simple content management system for reularly updating the products 5.) I need a simple user manual so I will be able to do the basics ## Deliverables I will need to populate a new logo throughout the site and genarate new copy on pages such as terms & conditions, sizing charts etc.? I may need to change some navigation buttons.
