Create Simple Ethereum ERC-20 Address & Transaction Create/Scan functions in NodeJS & Javascript

I'm looking for someone to create some simple NodeJS & Javascript ([login to view URL]) functions for a server-side ERC-20 transaction application:

NodeJS:

createAddress func: Create new Ethereum Address for UserA

addToDb func: Add to SQL DB: Token Address + UserA ID

checkAddress func: Read token address balance for UserA from SQL DB (ERC-20 Token)

sendToken func: Send tokens from UserA address to predefined address

withdrawTokens func: Send tokens from UserA address to user specified address

UserA can be an example global variable (i.e. an integer with value 100). We will modify the code to fit our application.

Client:

(web3) sendToAddress: send specified erc-20 token to predefined address

We understand these functions are fairly simple, so expected turnaround time should be less than 48 hours.

Please send us your previous Ethereum/ERC-20 related applications that you have made, and your expected turnaround time for this project.

Skills: Ethereum, Javascript, node.js
