Dear sir: I do not mean to discourage you but not so easy to find a trained professional for this job (90% = amaterus + scammers) here.
Anyway this project seems a FAKE (30USD)!!! I hope is not.
What you are needing is a complex calculation/optimization website.
I suggest you add some useful add-value feature like "van sharing", etc...
Price will be provide to you when we know all detailed specs, functionalities, requirements, ...
