In this case you would need to find out your total dynamic head. In basic means, since you will need to design your system around your well, you will need to gather some info. You need to know what model pump you have (model, brand, and type), how many gpm is it pumping, what is your dynamic and static water table, and all the parts connected to your pump and well. You need this info because you want to know if your pump is able to perform within a certain criteria. This is not as dificult as it may seem. If you get this info, I will be glad to help you.
