Dear Sir or Madam,
you wrote: "ELECTRICAL & SOLAR - Installation, Maintenance, Repairs or something about what we do in the logo."
Well basically that can be done, but logos should rather just communicate these things without having to write them. The entire what you do list is rather subtext.To be put into a Letterhead and onto your card,not into the logo itself. So the question is: What do you want to be done? Just a logo, or also letterheads, headers and/or businesscards?

Hi I appreciate your comments. We are looking for a log at the moment but the extra information is background as the company has up until now never advertised nor does it have a website at present or any more than one email account. We are looking to bring it into the 21st century but need to do this stage by stage. The designer chosen would I guess have the option to carry this through? We have not used this before so please accept my apologies!

If easier then we would look at letterhead headers and business cards.
