Database Design (will be MySQL)

My database design skills leave a lot to be desired which means for a current site I am working on I require someone who can quickly research any potential tables/fields I may have missed as well as designing/structuring the MySQL database. No data entry or PHP work is required ONLY the research and creation of a database. To give an idea of the tables that will need to be researched, the site I am working on will initially: Allow users to create shopping lists Allow users to track an inventory of stocked items in their home/office It will scrape multiple online vendors sites for current prices daily for multiple physical regions Allow users to create/save recipes to give one click adding of ingredients to shopping list (if none in inventory) I have an initial base to start from done in visio/pdf which the successful freelancer will get a copy of however primary keys etc. are just auto assigned as I have no thorough working knowledge of database design best practices. So to recap the work required: 1-2 hours researching tables/fields I haven't thought of, forgot, or might find useful in the future. 1 hour writing MySQL query to create the tables and updating visio file (or create another editable file visually displaying the tables and relationships) Please only include information relevant to what is required in your proposal (I don't need 20 links to showcase your non database skills) and also be aware that no proposal means you will not be considered. I am looking to award this project fairly rapidly so do not delay your bid.
