Ask HN: Remote developer and hourly rates in Florida.

Hello HN, I am a developer based in Pakistan. I have recently been contacted by someone in Florida involved in SAP B1 add-ons development. I have no idea what are the hourly rates in that region and what will be a reasonable amount to charge. Can you please suggest a rate?

Background: I have around an year of experience with SAP B1, and I had integrated Skype with B1, and also implemented a tool to integrate a POS machine with SAP B1. This isn't much work but I did get to know a lot of stuff about SAP B1. A caveat: I did this back in 2012. So its been an year, or perhaps an year and a half since I touched SAP.
