Now they want me to bring them a detailed SEO PLAN and strategy
That looks like work to me. Since you already have reservations regarding their honesty, I would suggest that you tread carefully.
If you 'need' the project and you have time to spare, I would give them just enough rope to hang themselves: e.g. write an action plan that is just vague enough for someone to completely mess it up. If not, then wish them all the best and move on...
