I have a script to delete Tweets. I'll delete yours for a small fee. I'll need your login info unfortunately.

You can specify date range, keywords, days of week, days of month, tweet/reply/retweet/like, newst/oldest 1000.

It can delete about 2K per day for now, so it will take some time for larger accounts. Other options cost around $75 and require technical steps but are same day.
