PVA's Required Daily

I need PVA's regularly. Any amount of PVA's required daily for sure. Rate is between $2.5 to $3.0 per PVA (Preferably 2.5) and need only fresh PVA's ( MAKE IT VERY SURE ) If anyone found used you should replace it surely and quickly. I need minimum 72 hours replacement guarantee. Whoever will provide low rate then $3 surely be preferred. Also do mention in PM that for how many hours daily i can find you online on yahoo/GTALK/SKYPE Any of them, whoever can stay online for more ours will also be preferred becasue i can order any time. For bulk my rates are low so tell me your rates in PM for: - Less than 50 PVA, - between 50 PVA to 100 PVA, - between 100 PVA to 200 PVA, - between 200 PVA to 500 PVA, - between 500 PVA to 1000 PVA
