Graphic Illustrator to produce Custom Pictogram (Icon) Set

Opportunity details: Digital images Set of black symbols on transparent backgrounds square thumbnail-size images small enough to attach to tweets (440 x 220 pixels) able to be embedded on webpages frequently, but not exclusively, use stick figure silhouettes, akin to traffic signs frequently use hand silhouettes to represent actions communicate to target user group's prior knowledge and visual conventions: American males older than 35 years, veterans, outdoorsmen often use or resemble resemble U.S. traffic navigation and hazard signs, national park signs, military graphics (FM 101-5-1 Operational Graphics), armed services and federal agency seals, national flag icons, financial/market symbols, medical/hospital signs, consumer symbols, food symbols, famous landmark icons, etc. Other Factors: I have basically built concept of every icon in PowerPoint. The problems I am having are these: I need a family of stick figures that are uniquely mine - different enough that they do not resemble any others (Google "stick figure set" to see what I mean) I have significantly altered copyright-protected art to make prototypes, but I know I need scratch versions to make these proprietary I am not an artist, and some of my prototypes with human figures just don't "look right" yet I need an artistic eye that can make the entire set of icons uniform - if someone is familiar with the system, when they see one somewhere, they instantly know it came from my website (brand) I want these to go viral, but any merchandising from them should remain mine. So I need to include, if possible, tiny © symbols to retain exclusive rights to use and distribution I do not have the skills or software to produce these as vector images Requires a service provider willing to sign a non-disclosure agreement (NDA). Will require your proposed schedule and cost before awarding work.
