5000 classic car dealer email list creation

I have 2400 car classic car dealer emails, and looking for 5000 additional new emails to add to my list. I am looking for someone to search the Internet for US and Canadian classic car dealership emails and compare them against my list. This job includes searching the search engine for classic car dealers by state and find new emails that I don't currently have. Search: classic cars for sale, collector cars for sale, muscle cars for sale, antique cars for sale, hot rods for sale, street rod for sale and so on, combine with the state name, trying to get all of the classic car dealers in every US state. Search Example: Texas Classic Cars, Texas Muscle Cars, Texas Hot Rods, Texas Street rods... and so on. You will provide an excel spreadsheet with the state, URL or the dealership and email or link to a contact form on the dealers site. We have already hit a few large classic car sites with directories of dealers, so the job will take a lot of hunting and cutting and pasting. Please reply with a price to locate 5000 additional emails not already included on my list of 2200, and include the amount of time you need to complete the job. I will set up a 50% milestone, and pay the second 50% email after the emails are sent and recognized as legitimate working emails. No more that 5% of the emails should bounce. Thank you!
