Hello,
Yes I've been in betting business for close to 10 years and I used to own a lot of websites (paid picks, free picks, systems, forum etc). So my list of subscribers is quite large + I bought a lot and I swapped a lot.
Please tell me what would you like to advertise. I am not interesting to sell my base because I know that value of it is so huge. But I can swap with you if you have also a good database.
regards
