Logistics Website -- 2

I am starting a courier/cargo business & need a website for the same. I have tie ups with leading global carriers like FedEx, DHL etc. I would like to integrate their API on my site & would like to give users (my clients) the ability to print labels directly from my site.

I would like the following features on my site
- User management (login, track, reports, rates etc)
- Development of API for my site for integration with my client who sell on various e-commerce platforms & sites
- Integrating APIs of vendors with my site
- Closed wallet for billing
- Tracking facility of packages connected
- Payment gateway integration
- User specific Mis reports (auto)
- Mail / SMS / Push notification
- Public Rate
- Serviceability Check / Transit time check
- Social media, Google
- SEO friendly
- Contact us

I would like the site to be light, device flexible

Further details can be discussed.
