Hi, we dont have experience with AWIZ but considering we did nats, stxt, smart tube pro, mech bunny and TONS of other scripts/integrations in php/smarty/custom templating engine + we do custom php coding (with or without frameworks like codeigniter), I believe WE CAN DO IT!
Check

[email protected] with work description/requirements + your budget.
Cheers, Ivo Polic.
