Research/Find icons for the site

Hello We need a web designer/researcher who can search for the suitable icons for our site. These would be small thumbnail icons and all of them should be in the same theme (carbon icons with same richness) as the site. You will have to go through the site and come up with icons at missing places. There will be around 50-60 icons altogether. You can use istockphoto or any other site to find the best match. We need png of jpg for each in a zip format. I will share the site in PM for shortlisted providers. Thanks. My budget is no more than $50-75
