Modifications to existing website

I need to have some minor modifications made to my Joomla website. The tasks include: -Delete an existing link to a page within site -Add new links to pages within site -Restore the rotating images function on an existing page -Add discount coupon in Virtuemart for a product -Adjust parameters of discount for existing coupon in Virtuemart -Change copy on button -Add 2 images, 1 paragraph of copy, and one link to an existing page -Add copy and link to an existing page -Substitute 1 paragraph of copy on an existing page -Change button on an existing page These are relatively straightforward but important tweaks designed to improve the the user interface and increase the conversion rate of a commercial site.
