Create images for website

Hello! I need someone who can create images (icons) to be used on the homepage which will link to the different pages. We currently have photo images that aren't completely relevant in most cases.

We will need images for:

"Medical writing services"
"Statistical service"
"Journal submission service"
"Abstract editing and submission"
"Journal selection"
"Proofreading and journal-specific formatting"

The website is: www.researchmedics.com
