Cisco SR520 3 Site WAN & VPN

I have 3 sites which will each have a cisco SR520W router with advanced ip IOS Site 1 Static IP on ADSL range of 5 addresses, will need configuring with DMZ to host IP Telephone exchange & Exchange server, wireles to be configured on local lan Site 2 Single static Ip on adsl, exchnage server to be hosted on lan access in for SMTP traffic to server only. DMZ for a external wirless point to allow unguarded access to internet and to 1 internal address for photocopier. Internal wirless to be configured on LAN Site 3 DHCP Adsl connection, wireless on internal LAN Site 1 is the primary site, Site 2 and Site 3 need to connect using permanet VPN, all lans to have full acccess to other lans, with routing and name resolution by the routers. Router to be used as DNCP server on all sites. Site 1 and site 2 to be configured for external VPN access to the network using cisco client. I will provide internal and external IP addresses to the winning bidder along with ADSL usernames and passwords. I require complete configs for brand new routers, I am capable of loading the configs on the routers First milestone will be released when all 3 sites have adsl connectivity with the new routers, final payment will be made when each site can browse machines and the VPN connectivity has been tested.
