Amendments to Joomla and Joomshopping website

I would like to make a number of small amendments to my website. These include installing a couple of modules and plug in as well as improving the layout of some of the pages. I am a sole trader and am looking for someone I can work with on an ongoing basis to make general improvements and additions to the website. Examples of things I would like to currently do to the site are: add an option to the 'how did you hear about us' on the checkout page of the website testimonials feed on home page (same as blogs) Improving the layout of the Advice Centre tab brand the Sage Pay checkout page add a text box onto each on the product pages to use the blank space below the 'Add to Basket' box. This would be static text that just highlights the benefits of buying from us Add a box on homepage with You Tube link 'watch us' Sign up for a newsletter box on homepage (and possible on every page) Find us on Facebook box Website is: [login to view URL]
