My apologize I have to withdraw my first rank because I received private message from another designer and he said that my logo is similar with another company.
My favorite M is design number #338 (#337 and #338 are same) or maybe you need simpler is design number #335.
Look forward to hearing something back from you soon. Thanks in advance.
If the brand name under the logo I prefer design #348 but if the brand name on the right of logo I prefer design #349 or design #565. It's up to you because you are decision maker.
Look forward to hearing something back from you soon. Thanks in advance.
