my new custmer

My friend is a IT company a vice-president. He requested me help him. The reason was a technical problem. His company has been doing special project . but It got a ploblem at technical. The ploblem has not solved for 4 months. so His customer was a upset. My friend told me you can solve that. and the ploblem is not difficult for me. I met his customer yesterday. and I met some project member before metting customer. I asked some situation about project. and I found bad problem. I thought maybe project manager did not report all problem . Anyway I had to convince customer. I succeed and my customer was safisfied. but I had a big problem and homework. The problem was a lot and various kinds. My customer has not enough time. He want to finish this problem until this month. but I had another schedule. I am very busy with my schedual right now. I will be more busy with schedual added.
