Cre Loaded Modifications to existing site

I have an existing Cre Loaded Web Site and need to add a new information page and make changes to the checkout process. Details below:- 1) Add a new page called “care page” and add to navigation at top. This to be updated via CMS 2) The site can take 3 currencies – British Pound, US Dollar and Euro (default). In admin, my client has to go to Localization/Currencies and press “update exchange rate” every day. Can we make this feature automatic once a day? 3) When a client orders a boquet, they want to be able to offer them a choice of sizes (small, medium, large) a think this is can be added using product attributes, please confirm 4) On the email notification to client, client wants the “order No” to be in subject line 5) The other changes are in the order process but I will give full details when I select a developer. I am looking for an experienced English speaking Cre loaded developer who has lots of experience with Cre Loaded customisation. Please provide example Creloaded projects you have worked on Thanks
