Design and code 10 HTML5/CSS templates for email signatures

We are the developers of premium office management software. We would like to empower out clients to quickly create beautiful email signatures for all users in their corporate environment. We need to create 10 HTML5\CSS templates for emails signatures, that the clients can choose from. Each template will contain a set of pre-determined data (e.g. user name, company name, user phone number, company address, etc). The user will be able to choose a design, choose their own logo, and choose which of the pre-supplied data will be used. User will also be able to choose from several different color schemes for the chosen signature. We need a designer to: 1. Create 10 templates in HTML5\CSS. 2. Only inline STYLE can be used - no HTML headers or BODY tags. 3. Designs must be as simple as possible and only use a minimal number of HTML5\CSS tags, so as to be as compatible as possible. 4. More specifically, designs must only use tags supported by all mail clients and browsers, as specified here: [login to view URL] 4. Designs must look good on computer monitor and mobile devices. 5. Designs must use some arbitrary logo as an example.
