Hi!
I have gone through your blog and checked the images. I have past experience in designing blog images and skilled in illustrator and photoshop. I shall design simplistic style images with commercially free stock images & illustrations (legal, yet pocket friendly) or typography. The images will be clean in design yet stand out to emphasise the blog post. I shall also help you with the images within the post (I shall edit the screenshots to highlight texts, magnify certain areas, adding instructions, etc). The bid price includes all such images and the header image for a single blog post. We can settle at a reduced rate for multiple blog posts together.
If you like my style, you can hire me for future posts too, I'll be glad to help. You can suggest unlimited changes till you are completely satisfied.
