So to calrify, are you seeking a 'safety vest' graphic/illustration/template in order for you to have manufactured? Or are you wanting a design that you will be able to imprint with you graphic design work? Are there companies out their that will produced custom safety vests? Please let us know. Thank you in advance.

Thank you for your question. To be honest my original intention was this.
"We are looking for safety vests for our techs in the field that are made of our logo colors, probably the blue and green. Like a two tone safety vest, top and bottom potentially, and then our logo on the back of each vest so that clients can easily tell who is on their property. Potentially something that has a 'black bottom' area on the front section. The material needs to be light and help keep the team cool in the summer.
Also, we need some long sleeved shirts for our chemical application technicians. In the past we've used the fishing style shirts that button up the front and around the wrists. That way if the techs get a bit warm they can always unbutton a few buttons to increase airflow. I can see these shits including our logo and color scheme somehow. Also, having a bit of ansi material worked into these would be good sense all of our techs work from the road on a daily basis. These would most likely need to have that 'black bottom' on them as our techs always get dirty. Also, may want to incorporate the 'black sleeves' up to the elbows as well.
Ideally we'd like our truck design, our in the field technicians vests and our in office executive/support staff to all match somehow colorwise. The folks in the office or management positions, we would need a professional style shirt, with a collar, like a polo. Again, something lightweight and breathable to keep everyone cool in hot temps. Probably wouldn't need the 'black bottoms' on these.
We'll want some ball caps made of a netted material that breathes super well. Again, matching in color with our logo on the front. Also, probably some sun hats of sorts. Maybe bucket hats? I've used the straw sombreros in the past. I guess whatever you have available to keep the sun off our techs.
Also, some t-shirts that are moisture wicking and breathable. These we'll want to tie into our general theme of tying everything together. Logo, color, etc. These won't be our normal uniforms, they will be for guys going to training, events, etc. The 'black bottoms' wouldn't need to be included on these. I foresee our techs maybe wearing these under their safety vests if they have them on for that day.
This will get us started but we'll want to add to our apparel as the seasons change. We plan to do a fair amount of snow and ice control services for the winter time."
I understand design crowd approved my posting then asked me to amend it to only one item. My first time using this site.
To answer your question. I need all of the above, like a custom company brand. Being new to all this and design crowd not be helpful, I've navigated my best. Not really sure where to turn for help.
