10 - 20 simple logos creating

Information for the business: Mobile app
Industry: Internet/Software
Type of logo: Word mark, Letter form, Abstract mark, Pictorial mark, Emblem, Character
Ideas for the visual style: mixed ideas
Where the design will be used: Inside a mobile app
Extra notes: I have a software application we sell to the field trade industry (plumbers, electricians, builders etc). Our software powers their invoices, quotes and much more. We would like to provide some 'blank' logos for these businesses to use if they don't have one.

I'd like a range of basic 'flat' logos, for example spanners, tap, saw, digger, building etc

These logos shouldn't have text on and I'd like between 10 - 20.
