Logo for a Chartered Accounting Firm

We need someone to design a logo for an italian Chartered Accounting Firm (like american CPA certified public accountant). We require at least 5 different logo idea's to choose from. The logo's must be clean, Traditional Warm and Serious, and based on text only - The brand should be M, the initial letter of Firm's name (a stylized M that characterizes logo) coloring the logo in dark blue+ the full name "Mento Studio Commercialista" But M brand should also be used alone Mento = name's accountant Studio Commercialista = Certified public accountant See the logo in attach to get an idea of what we mean. We work only with expert graphic designer! Please only take this job on if you are 110% confident you can deliver to our brief. Anyone who can supply a mock up logo at this stage to show their skill will be at an advantage. Once we decide upon the final logo we will require it in a few different colours so we can re-use it. We would like it supplied in psd format with layers so we can re-use the logo within future adverts / business cards / etc that we use. The logo will eventually be used in press advertising etc so needs to be of a good enough resolution to be able to be blown up to A1 size if required. Do not bid if you cannot provide samples and a history of previous work. All the work must be original, unlicensed, and fully released to us. Additionally, the work must be provided in a multiple formats (JPG, GIF, PSD, EPS, etc). Thankyou!
