Magento site tweaks, SEO and Submission

I have a website built from a magento template. It is fully functional at the moment and all products have been populated etc. However I would like some small tweaks to the design which will require knowledge of Magento. These are mostly minor changes and will not take long for somebody that knows Magento: 1. (This is probably the most difficult change) Currently I have one main category with many sub-categories. Therefore the menu bar at the top only shows the main category. I would like the menu bar to show the main category, and also the custom pages such as 'Countact Us', 'FAQ','News/Offers'. These pages should 2 columns, the left one showing the categories, and the central column free HTML. 2. I have 9-10 other small changes. These are very minor things such as 'Decrease spacing below the top menu' and removing/chenging certain text. These should take no longer than 5 minutes each. 3. SEO/Submission/Link Building. This project will be offered to somebody who is good at SEO. Our aim is to get the website high on the first page of Google UK for the keyword 'canvas prints'. I know the basics of SEO and when building the site I incorporated keywords and meta-tags etc. However I need a SEO experienced person to look at the site, suggest and make any necessary changes to get the pages ranked highly, to submit the site, build back links etc. **I am willing to offer a Bonus if the site ranks No. 1 in Google UK for the keyword 'canvas prints' within 3 months, and remains within the top 5 results. In your bid please let me know what Magento and SEO experience you have, and previous SEO success.
