Need procurement/purchasing/sourcing contacts of US on a montly basis

I am looking to find someone who will help me in finding contacts (Manager/Director/VP) for procurement, sourcing, purchasing, etc in a list of US based companies. I already have good list of contacts but I am interested in adding to my database. So, will be interested in receiving 70-80 unique contacts on a weekly basis. I would prefer the engagement to be monthly where I will pay a fixed amount for the month and would expect in return 280-320 contacts in a month. I have a budget of INR 7000 to INR 12000. Feel free to IM me in case you have any questions.
