Data extraction

I need to extract data from a website that updates their data every 5 min. The extracted data will be validated for a certain condition. If certain condition exists data is kept and tracked to see if it fulfills all other conditions. If the data kept fulfilled all the conditions, it is to display the data that fulfill all the conditions in a certain format. If data does not fulfill any condition at any point it is being monitored, data is dropped. I am not a very technical person so you have to tell me what I require in terms of hardware and if software should I need. Data is being updated every 5 minutes. There will be between 200-300 data that requires validation at any time.
