Design Blog Post Images

Looking for some blog images created for my blog posts. Ideally, I think I will need two images per blog post. One that is Twitter friendly (1024x512) and another that is Pinterest friendly (at least 735x1102). Each image must have the title of the blog post and the watermark/logo of the website (I will provide this). There are a total of 25 blog posts that need images. For the most part you can probably do the large Pinterest friendly image first and then remove elements/resize it for Twitter. The topic of the blog is digital marketing, social media, seo, etc. So the designs should be inline with what most would expect on this type of site. If you want your bid to be considered, please provide a sample of the two image sizes for the same blog post of work you have done, or on the same topic/title as the attached image of the Twitter sized image for a blog post. Please let me know if you have any questions.
