Your code doesn't show the images because you are referring to your C drive. What you should look at here is setting the position of the text to absolute in your CSS, and use relative positioning from there. Because I can't see your underlying images, I can't position them appropriately, but you should start with something like the following and play around with your margins or padding as appropriate.
.about-us-text {
position:absolute;
text-align: left;
box-sizing: border-box;
align-self: start;
padding-left:460px;
padding-top: 0%;
padding-right: 25px;
}
