How do i figure out how much SBD to use on a post? I have 30 SBD so, should I use like 1 SBD per post?

Do I send SBD immediately after posting a new content only or I can use old content post too via above mention promoters?

Some on their profile will have a "specific" minimum amount of SBD that you need to send. Most bid bots won't allow bidding of "older" content ... usually that's content 3 days or older won't be allowed. Again, each bid bot is different. You'll know if your SBD order won't go through, as the bid bot will reply back stating "not enough SBD", or if bid round is full, then they'll just roll you into the next bid round. I don't think @therising or @appreciator has minimum bid amount (I could be wrong so check) ... but I know @postpromoter is at least 4 SBD and @buildawhale is at least 5 SBD (and with that, also have to wait at least 20 minutes post age for buildawhale).

How many days average above mentioned bots will promote a content?

Do above bots have a calculator i could use to figure out how much SBD to spent to get certain ROI per content?
