Researching various websites for certain information

I'm looking for someone to help me gather information about the internal dimensions of cars, specifically the length, width, height of the load space in hatch backs and estate cars with and without the seats folded down. Also the opening space. Also the size of the boots on normal saloon cars. This is related to a parcel delivery project I am working on. These dimensions would need to be gathered for each make and model of car eventually, but I'd like to start with a list of about 30 or 40 at first just to see how things go. 2 ways of going about this I can think of: Internet research: Looking at relevant car make website. I know some of this information on some makes and models can be found online. For the cars we can't find, another way is to contact sellers on [login to view URL] and/or Ebay Motors who have the relevant car for sale and ask them to let us know the required measurements. I'm sure they would do the measuring for us thinking we might be interested in purchasing their car for sale. I would imagine a couple of copy & paste email messages (one for car boots and 1 for hatch backs and estate cars) would be sufficient. I would provide you with a list of cars (make and model) and ask if you could obtain these measurements for me. Whether you'd like to get paid hourly or maybe when we get going you'd like to make a little more money if we worked out a price per car, I'm open to ideas. Ken
