Hello,
I have read through your project. I have prior experience in data mining from websites. If you can share reference url, I can mine sample data and send it in Excel sheet for you to be more sure, and likely to award the project to me.
Also, if the mined data is inline, and as you mentioned, if it's recurring project, we can discuss on possibility to mine the data regularly, temporarily store it on my cloud storage and provide you an access via API. This could help you to save cost on recurring data mining, drastically.
I have bid at lowest cost for this project, so that you could rate me and post a good review. Assure a timely delivery.
