Yes, either a competent architect or a structural engineer can help you, AFTER he or she has seen the exact conditions first-hand. I don't believe it is either ethical or proper to give such structural advice in this forum, because often the information given is incomplete or partially incorrect, and the exact configuration of the structure MUST be seen.
