Configure Mikrotik RB951-2n

I'm looking for somebody who can configure my RB951-2n. Budget is $30. Nothing more and nothing less. Don't bid if you cannot do it for this budget. eth0 is connected to our ISP (DHCP client) eth1 grants access to the office network without authentication (and gives out DHCP lease) users connected through eth2/eth3/eth4/wl0 needs to authenticate via the webform. Their username and password gives them access to either - the office network - internet only (+ client isolation) We don't have big secrets on our office network, so the office and public network don't have too be deeply protected from each other. It would be cool to be able to create user vouchers which are time delimited and to have some basic bandwidth control over them. Also it would be cool to be able to make unexpiring login-password combintation for regular visitors, office people and mac addresses. I can use the standard internal interface for generating the vouchers etc. Only need the basic configuration file.
