I need a logo design

Information for the business: Offer a support service via e-mail, telephone, and webcam
Type of logo: Word mark, Pictorial mark, Emblem, Character
Brand name/slogan in logo: myhero.io
Number of revisions: unlimited
Ideas for the visual style: a computer with a mechanic on screen
Preferred colors: primary/simple
Where the design will be used: print, web, marketing material
Extra notes: We are launching an online marketplace which deals with training and support delivered via webcam, messaging, or over the phone.

The site is a marketplace much like PPH, with technicians/experts advertising their skills, and customer posting job requests.

Initially we are prepared to only offer IT support, however we are quickly expanding in to household maintenance, as well as other specialist sectors such as car repair and plumbing, so the logo should not be IT support specific.

It will need to be very visually appealing to the non expert, and should encompass what service the website provides.

The logo should incorporate the website URL myhero.io, as well as some pictorial graphic.

I will require all potential proposals to provide me with a quick mockup of some of their ideas. Once you are chosen based on your initial design concepts, I will require multiple mock ups so different logo ideas can be explored, and unlimited revision (a reasonable amount).

I will require all work to be provided in vector format.
