Cryptocurrency Idlecpu.com / Programming web miner

If you want to see a basic layout of what we are doing you can go to [login to view URL] which is an incomplete site which we need someone to finish and replace the coinhive miner. In more detail: We need a web based miner using both the CPU and GPU. This can NOT be an implementation of coinhive or another existing program. This miner needs to be unique code and will only be run on our site where visitors want to run the code to help donate to charity. The web based miner must be at least 70% as efficient as a stand alone miner like xmk-stak, ccminer, cgminer, claymore miner, etc. It also needs to contain a slider to allow the user to select a level from 1 to 10 for resource usage so this can run in the background with minimal effect, or it can be turned up to 100% and fully use the CPU and GPU. It also needs a "stop" / "start" button so that all mining can be temporarily stopped and restarted by the visitor. The mining page that currently exists as a separate page after clicking "Click to start donating your unused CPU power" should be on the main page and not be a different page. This should allow mining to be started right from the main page, with a list of charities where a radial button can be clicked to select which charity the mining is for just above it. If a different button is clicked while mining it should change the charity being mined. There should be an option to create an account for those wanting to keep records of how much they have donated for tax purposes. This should then keep track of everything they have mined, and they should be able to print a report showing each day what they donated in USD to each charity, the total of what was donated to each charity, and a total amount donated to all charities. On the main page there also needs to be a direct donation link using PayPal. This is way too big on the current mining page, but we still need the ability for people to donate directly. The main page needs to show statistics in more detail than what is currently displayed and this should be geared towards the general public, not a miner with crypto experience, so we don't want to talk about "hashes" and XMR mined, but instead word things as something like CPU cycles and USD earned. It should have statistics that continuously update on the page showing: 1) All time total raised for ALL charities in USD. 2) All time total raised for each charity. 3) Total raised by the user for each charity. 4) Number of users donating CPU time. 5) And more states to be added as part of this project so please keep this in mind when quoting the job. This needs to also have a backend where it tracks a lot of information and offers options that only we see including: 1) Set the wallet addresses for each of the charities so when selected the coins go into the correct wallet. 2) An easy way to add new charities. 3) Each charity should have a percentage that can be set in the admin area (not visible to others) that is kept for administrative costs so that percentage goes to a separate wallet (need to be able to put this wallet address into the admin) and not into the wallet for the charity. 4) At midnight EST every day it should take the amount of coins earned for each charity and record this amount in the database along with the date and the current USD value. This should then reset to zero for the next day. We need to be able to see how much was generated each day for each charity in a report saving full historical data as to how much was earned. 5) We should be able to select any mining pool in the backend. The miner should be able to mine CryptoNight based coins with the CPU, and with the GPU mine Ethash, Neoscript or Equihash, with the ability to change to multiple different coins and pools automatically choosing whichever is most profitable at the time. 6) There will be other information and specifications needed in the admin so please calculate extra time when quoting this job to add these things.
