Hello!
I'm working in web industry for 18 years, and i can do your job fast and trouble free. I can add some profesional looking flash banners to your site, displaying some great offers. for the "contact" page i can add aslo a "live help" addon, or skype buttons. Usually i do some SEO/SEF, even for the low budget projects.
Here is my view:
Stylish design, SEF url's and menus, live (skype, msn or other) and e-mail contact with any number and types of fields.
time i need: 24 hours, but make sure your hosting are joomla compatible.
