Need a desktop software to fill form and click submit.

Hello, I need a desktop software to post to a website. I have data in txt file and images in the folder. It will fill title (getting the data from txt file). It will fill price, it will multiply the price with 1.5 + 50, then it will fill price. There will be option for me to change the price on the software. It will upload all the images. Then it will fill the description, it will replace some part of the description from another common txt file as template. It will select location, new and for sale radio button. Then it will click submit. There will be a simple GUI so I can use the software easily. Need the software done in 24 hours because I don't want to waste time. Budget - $80. Thanks. I actually have a macro doing this process just fine, but it takes 2 and a half minutes to post 1 product, I want to post 1 product in 30 seconds, that's why I need a software, so it should post quite fast, also one more thing, there will be a delay option, I can enter how many seconds it will delay after posting 1 product.
