Portal (Flash needed) and Microsites design and development

I'm launching a business in the UK with a focus on 'Niche' PR and Events services. Niche because high profile clients will be targetted and the principles of social media and e-commerce will also be adopted. Along with this, I'd also like to Enable Multiple Revenue Streams on the website in order to do the following: * serving adverts/selling advert spaces * adding affiliate links * charging for subscriptions to premium/web content content * selling stuff via online shop (eg, tickets to upcoming events and merchandise) * promoting offline events *Multi language platform giving the viewer/surfer 3 to 5 languages to choose from. Member database: This is also another avenue by which we hope to generate and create a database from visitors and subscribers. I'd like this to be searchable, exportable and easy to customise. Perhaps laid out according to regions or country. Integrated Payment Processing. This can be used to charge for membership / subscriptions, product sales and generate income from other services. The main website of the business will be the 'Hub' which in turn defaults to other sites of which domain names we have acquired already. We have 2 high profile clients already (domain names acquired) and pictures and videos from a few events we put together. I need help with designing and developing a good portal and websites to complement the business. For all of these, I'd like a flexible design interface where I can easily tweak and adjust the website easily and quite quickly without having to wait on the webmaster as this may prove crucial with regular uploading of data. The following are some key areas needed: Search Engine Optimization Multimedia Content (for music, videos etc) Image Library Download Library Relationship Building Applications; e.g: * RSS feeds * forums * comment fields under articles * Email/newsletters * Blog section Integrated Login and Password Access Monitoring, Security and Backup Continuous Support.
