Send DMs manually on Twitter and Instagram

I'm looking for someone to send a cut-and-past message to our own Instagram and Twitter followers. We'll need to keep to the daily limits as so not to block the accounts and should be done for 10 consecutive days - at which point we'll review the results and determine whether or not to continue.

Could you let me know if you're interested in this project and, if so, provide a daily hourly expectation of time commitment and an overall quote for 10 days.
