Magento Modification and Speed Enhancement

Website: [login to view URL] Here is the list: 1) Fix minor layout issues, i.e. enlarge pop up box slightly at the bottom so you can see the icon when added to cart, check missing tick boxes in related items i.e. [login to view URL] 2) Modify current 'Contact Us' form, adding 2 more text boxes: After Telephone text box ad a text box for 'SUBJECT' with a drop down menu with options - General Enquiries, Order Enquiries, Returns & Cancellations, Technical Site Issues, Other. Then after that box put another text box for 'Order Number'. Then 'Comment' box is the same after. 3) Add Youtube video on homepage (taking out twitter feeds section) and add header box 'INTIMATE COLLECTION' add youtube video box below it (I will supply the youtube video in the next couple of days). 4) Add Blog page to website matching the style, add Blog box section in homepage (taking out twitter feeds) add header box 'BLOG' with text below 'Check out our Blog' (hyperlink to blog page) (I will do the blogging). 5) Modify invoice layout i.e. take out 'Sold to:' and change 'Ship to:' to 'Deliver to:' take out prices and tax and add text to the bottom central 'Thank you for shopping with Intimate Collection'. If you have a nice invoice layout to use with my logo that would be great as the current one is not so appealing... 6) Styling boxes for filter headers i.e. Price, Colour etc. in category pages. To match the rest of the page theme. 7) Add option to buy 'Out of Stock' items, (backorders if below 0 quantity). (pop up box on screen to explain - 'Sorry we are Temporarily Out of Stock - Please allow up to 14 Working Days for Delivery'. 8) Add new feature on the Newsletter section on homepage - replace text to 'Get 10% Off your First Order when you Sign up to Our Newsletter'. (Auto generate an unique coupon code and send email to customer). Put email on transactional email templates section in Magento admin so I can see and possibly re-word. 9) Take off the .html at the end of the website address. (not sure if this makes much difference or do we need it on...). Pls advise. 10) When deleting an item on the shortcut shopping cart on the top right corner of page, you get an message 'Your Item has been is Successfully Deleted' can you put a space after it so there is a space between the 'Shopping Cart is empty' box and 'Shopping Cart' Box (when deleting 1 item from 2 items it takes you to the shopping cart page). 11) When logged in, and at shopping cart with an item to purchase, you have an option to 'Move to Wishlist', when you 'MOVE' it, you get a message 'xxxxx has been moved to wishlist Wishlist' can you change the text to 'xxxxx has been moved to your wishlist.' Speed Enhancement: Fix 'Yslow' and GT Metrix speed enhancement issues i.e. specify image dimensions, fix W3C errors, add Expires headers, avoid AlphaImageLoader filter, make fewer HTTP requests, minify JavaScript and CSS, defer parsing of JavaScript etc. etc. Thanks Biswa
