I have an opportunity to acquire an 8x8 square steel building. It has windows all the way around the sides, from floor to ceiling. The floor and roof are steel. It has a sliding door and 2 windows that open. It was originally a shelter at a bus stop. Will it work as a starter greenhouse? I am concerned that the steel roof and straight sides will be a problem.

As long as it will retain heat well and get plenty of sunlight, this should not be a big problem. Just make sure to adequately ventilate it so that it doesn't get to hot or moist inside, which could ultimately burn plants or lead to fungal issues.
