Hi,
I have previously completed a very similar project on freelancer.com for building a chrome extension, for scraping images from search results from Linkedin, Facebook and Instagram using a chrome extension. Hence, looking at the project details, I should be able to build the plugin with exact requirements in quicktime.
The hourly rate is somewhat less than I usually charge, hence I am quoting something in between. However, since I have experience doing a similar project, I should be able to make up for it by doing in quick time.I estimate 10 hours of work looking at current requirements. I will be able to give more accurate estimates once we discuss project specifics.
