Hello John, this is Archie and I'm with Jumpstart Capital. We specialize in financing for small businesses and we have very competitive rates. Please call me back at 800-123-1234 for a free, no-obligation quote!

Good voicemail message (industry specific):

Hello John, this is Archie and I'm with Jumpstart Capital. You and I haven’t spoken yet, but I’ve been doing some research on your company and I think you’re a great fit for our financing program for general contractors. Our clients include (list some companies they might be familiar with) and I know this would work for you as well. Believe me, it will be worth a 5 minute phone call to find out why. Please do me a favor when you get this message and call me back at 800-123-1234. Again, that number is 800-123-1234. I look forward to speaking with you and I guarantee you'll be glad you returned this call.
