this was my college calculus textbook: https://www.amazon.com/Calculus-7th-James-Stewart/dp/0538497.... I can't comment if it was good or not because by college, I had taken calculus twice so it was all a refresher
best of luck! You sound educated enough (yes, I'm judging from the couple sentences you wrote) that I think you won't have any problems acquiring math knowledge with persistence.
All of these intro texts (at $150-$200) are broken. They do not go into the subject matter deep enough to use as reference later in coursework or a career and their too expensive to disseminate knowledge widely. Realistically at $30 it's still too expensive to compete with free. But until annotation and referencing UX catches up for e-books dead-tree books still win for learning (I know people manage with PDFs and annotation, but I haven't had success with e-books for anything except for recreational reading). And I think there is a hurdle that is difficult to get over with getting other universities to adopt a university press book from a different university especially for an introductory text.
