Need US-based Phone Numbers for Craigslist PVA Creation

My project is similar to another project posted on GAF. I am looking for USA Phone Numbers for PVA creation, with forwarding to my number of choice. What's important to me is a high success ratio when creating PVAs. I don't like creating PVAs and wasting a lot of time to get a call that never comes. For all non-working numbers, replacement within 72 hours is important. I am looking for a long term, win-win relationship here. The number one thing I'm looking for is reliability. The numbers must work for PVA creation. Please reply with your offer if you can provide USA phone numbers that work for CL PVA creation, with forwarding to the number of my choice. I would like to buy 50 numbers initially to evaluate, and if your work is good, I will order hundreds more. Thanks.
