order system like onehourtranslationdotcom

My client need a website for translation business that requires development.
We need the same 'Instant Quote & Order' system like the one on the onehourtranslation[dot]com homepage.
I'm designing the whole site except that part (Quote and Order system).
I'm using WordPress in Linux server.
We need exactly same 'Instant Quote and Order' system including checkout page, payment processor integration.
Also, admin can get/manage all the details on the WP admin panel including files (or texts for translation).
There, you can choose from the four services:
   Translation, Proofreading, Transcription and Translation+Proofreading from above of the order form.
If you upload any files, words will be counted automatically and the price will be updated instantly.
Needs Alipay, PayPal and Offline Bank Transfer(orders manually approve by admin) as payment processors.
There should be an area in the admin panel where admin can add/edit settings (languages, price etc) for the order form.
The main point I will mention is the automatic words count system after file uploading.
I mainly need popular file types:
   ZIP, MS Word, Excel, PowerPoint, PDF, TXT and if possible other document formats too.
After little searching, I found that Apache Tika may help to achieve this but I don't know what you will use.
Files should be stored in the local server, but it would be great if you can integrate Dropbox or Amazon storage or anything similar for file storage.
Btw, I don't need filepicker.io service that the example site using, just simple file uploader will be ok.
Also, there will be a user registration/login system integrated with the ordering system.
And logged in uses can see their project progress from their account.
Admin can define the project progress percentage from admin panel.
You can use WooCommerce or anything you want to develop this.
I need the system as a different plugin or you can add it to WP theme directly (plugin will be better).
And, it would be great too if you can provide shortcodes for order form, checkout page and user account (project progress).
So again, I'm designing the whole site, you only have to do the order system development that I described above.
Only serious bidder bid here.
