Develop or complete a website on Drupal7

There is an unfinished website on the drupala7, but it is necessary to finalize the functionality, according to the technical task, screw the system of input / withdrawal of funds "Single wallet", comb the site, screw any ready-made design or develop your own (you can with the involvement of other friendly freelancers), delimit the rights of administrators and moderators, make two simple requests, move to another domain, integrate with social networks.
The archive has 3 files:
doc - the full technical task immediately address the site.
xls - current unfinished tasks
vsd - block diagram of the site (white blocks - "horse did not lie down", green - ready to comb, faded green - need to be finished).
Of course, I am considering options to write everything over or abandon part of the functionality, please note that the main thing for me in this project is the price, so please carefully read those. The task is to name the price for the entire project, not the cost of the hour. No need to send empty applications without the cost of the project.
