Joomla, XXO Cart Expertise Required

I require someone to work hand in hand to service the needs of our clients questions, issues and updates of a new Shopping Cart site currently being built. Please see below the various items currently requiring attention. We need short quick explanations for some items and technical work carried out for others. All atwork and info can be provided as needed. We would like to work with this person on a pay as you go basis for example, each time tasks are completed we pay for the completed tasks. I am setting the minimum budget but that may be for parts of the questions below and we would continue to 'pay as you go ' from there on. 1. We need a default Shopping Zoo logo for any product that does not have a picture 2. Please show me how to have products in multiple categories without duplicating 3. When you open some of the products the info on the bottom of the page gets squashed up – contact us etc 4. Please show me how to add a default pic to many products – let’ say for eg. Brother ink range 200 products that have no pics can add Brother logo with time consuming adding one at a time, you will see this in the Lanier range, this took ages. 5. We need to link up when a client presses the request info button to go to an enquiry page 6. Please design an enquiry page with drop down menus – Name , Phone , Email , what is the enquiry about or to be specific if a client is requesting more info on a product , this needs to be streamline that the product it automatically added to the enquiry form 7. When a client selects a product we need a form on the bottom of each page for additional information – for eg. Flowers , we will need address details , phone , personal message , colour of flower or if it is a business card job we need options to add more info or attachments. 8. On the front page we need have an even 12 products not 10 , can these products on the front page change every time you refresh the page ? 9. Shopping Zoo blurb at the top on the front page. We need to change it to the same info as the back of my business card. 10. If you look at some of the monkey icons on the front page they seem to be cut in half on some of the buttons 11. Hot Deals – Not all of the Hot deals are landing on the front page , even if I select it in ixxocart 12. Online chat – Customer Support – Same as your site 13. Games – we need to have more reason for customers to stay on our site – basic games , same as facebook , need a free license etc ?? 14. When you go into placing a Free advert there are 3 features at the bottom – If a client selects Employment we need these features on the bottom – Salary 15. If a client selects a product to sell we will need , kind of delivery , condition and price 16. Create generic 10% GST on all products default unless I deselect for products like Mona Vie ? 17. I need Shopping Zoo Banners created for the affiliates section 18. Let’s use the button – best viewed with Mozilla – download here etc
