Hey Victo!
Way to keep coming back strong… SAND strong!
This 
SIP: Ideas category is a place where you can develop your idea (including deciding upon the best possible amount for funding request).
Community feedback and the input from @Delegates and @domainallocators should help you further develop/clarify the idea (deliverables and execution) and the needed funding amount.
So, through discussion on this thread over the days/weeks ahead, hopefully you can fine tune the language and come to a number….
