Quick Private IT Infrastructure Consulting

I have a diagram of the network setup I'm thinking of going with. Please PM me and I'll email it or PM it along with my questions. I notice we actually don't have a specific networking forum which this may fall under, but a lot of what I'll be asking will be the type of hardwares/models I need for firewalls,switches,etc so I decided to ask here. Being that my network hardware would be kinda known I'd rather PM/email it anyone willing to help me. I've got a good bit of networking experience but it isn't my strong-suit, however, I've been asked to do this project and I want to make sure my T's are dotted and my I's are crossed.
