Welcome to the Forum! :)
Lease and lessons for just $150 usually mean one thing: it's better to stay away from such "lessons". Your best bet still would be to look for group lessons (those go for $30-40 in my area, so you could do 4-5 lessons/months). You can also consider volunteering in rescue (if there are any around) or helping out in barn in exchange for lessons.
