3 Email Newsletter Designs for Use in MailChimp Campaign

We require five differing email newsletter templates designed and coded so non-technical users can create weekly and monthly newsletters within MailChimp using their 'template' edit functionality.
The templates will need to pick up the look and feel of two existing web sites - in terms of colour, fonts, style - with the structure of each template being largely fixed - with users adding differing text, hyperlinks and images each week or month.
Two of these templates are needed urgently - this week if possible - the other three are required in the next week or so.
If you need clarification please ask ANY questions.

All templates will need to be installed into Mail Chimp, and proven to work.

With your proposal please give examples of other newsletters or relevant design work you've managed/implemented. We will also require confirmation that you can deliver against the specified timescales.

UK bidders preferred - we will need to brief and liaise by phone during normal working hours
