Well i guess that 1k per month is not issue at all, specially on 3 months old account so that is excluded as limit reason. What main problem could be is how you create accounts and informations you use on them. I would suggest you to go with paypal stealth account (google more about that if you are not familiar with it) basicly it is creating new paypal with fake infos on new windows user account or virtual machine. If paypal would link any same information on new paypal which is already entered on limited one = instant limit, same ip = limit. So if it is easier for you just create new user account on your windows and make new email, paypal and everything there and try then, use only that useracc for logging. I am not sure how will payments from same website affect but i think it shouldnt be big issue. Goodluck!
