Develop a Corporate Identity

Hi, We’re in the process of setting up a data entry company and I require a brand designer to basically give my start up an identity. I have some rough ideas as to the colour schemes and fonts I would like to use – but mainly I just want to project a professional services image, with a slightly up to date twist, as the name of company suggests, dataQuirk. I've added a rough attachment as to what we're working with... I’ve decided against a logo, and instead want to pursue a typeface only, e.g. like Microsoft. I’m not entirely sure what brand designing entails – apart from the obvious typeface, and colour schemes, I think we would also require specific detailed styles set up in MS Word and Excel to ensure consistency in documents and for meticulous subjects, as well as electronic letterheads, and potentially business cards. As we are a new start up, funds aren’t expendable, hence my main question is what would you charge for a project like this? What features can you offer that will beneficial to us? Thank you very much for your time – We look forward to hearing from you.
