Data Extraction for a few manufacturer websites

--iouapd
I am looking for data extraction from various manufacturer websites that would extract to an excel format all the fields of and descriptions of their products into an excel document. In addition, I would like to have their image saved as the item#. There are approximately 10 manufacturer sites and within each site there are approx 2k items for extraction. Therefore approx 20000 line items and images. I'm willing to pay $0.05 per line! So if you are a great coder, you can program and just extract and continue to make money.... I will also have this type of task on-going for other manufacturers and for newly listed products... Therefore, this could be a great revenue stream for you.
 
shopping cart data extraction
Hello, I am looking for a company that is experienced with extracting data and prices from a shopping cart online.
I have a list of 72 web-based sources of used cars in the UK, and need a Perl module written for each source to extract live car data from the source's website. Some of the sources are just a simple list (or collection of lists) of cars, but most employ a search facility that needs to be queried with appropriate arguments. The module structure is already defined, and must be adhered to, in order to integrate with our existing code.
I shall provide the following:-
- list of used car sources
- Perl module and supporting modules
- instructions for writing a car search module
I would require frequent feedback on the coder's progress through the list of sources, and regular delivery of code in exchange for regular payment.
Horseracing data collection
I will try to describe what I want to the best of my ability but please excuse my ignorance when it comes to technical terms as I am really out of my depth here.
I am looking for some one to write a program that will automatically collect daily horseracing data from a specific website www.racingpost.co.uk allthough the website is open to the public and all the information is freely available for personal use it is password protected in order to view the data stored.
I want something that will automatically collect
horses name,weight,days since last run,trainer,jockey,trainers course strike rate,jockeys course strike rate,trainers current form (%) jockeys current form (%) expected starting price there are likely to be one or two more criteria as well.I would also like certain figures to be highlighted if they pass a certain figure,for example any jockey whose winning rides at the course exceed 10% would automatically be highlighted in blue.
I have been struggling along myself copying and pasting alll this data into a spreadsheet but it just takes to long to be productive and ideally the program could do this for me and open either in a spreadsheet or in a PDF document.
I am sure I have missed out loads of important bits of information but that alll I can think of at the moment so please feel free to ask me any questions.
I will include a test username and password enabling you access in to the site from there you can view all data.
