The person this service is for wants the watch time itself, not a decorated player
The buyer this fits wants more public long-form watch time on videos that already exist as regular uploads, and is not counting it toward the Partner Program or any other monetization test — bought hours must not be used that way. They are not trying to make one watch page look busy for a sponsor. They are not trying to feed the Shorts shelf.
If your actual problem is “the counter under the title looks small,” that is the views service. If the file is vertical and lives in the Shorts player, that is the Shorts service. Buying hours to solve either of those spends money on a ledger the surface you care about does not read.
Order only if the hour total itself is the job. Everything else here is there to stop the order being sold as a salary.
