You can create your custom form template using LiveCycle and then data bind the form fields using iTextSharp like this

string randomFileName = Helpers.GetRandomFileName();
string formTemplate = Server.MapPath("~/FormTemplate.pdf");
 string formOutput = Server.MapPath(string.Format("~/downloads/Forms/Form-{0}.pdf",    randomFileName));

PdfReader reader = new PdfReader(formTemplate);
PdfStamper stamper = new PdfStamper(reader, new System.IO.FileStream(formOutput,   System.IO.FileMode.Create));
AcroFields fields = stamper.AcroFields;

// set form fields
fields.SetField("Date", DateTime.Now.ToShortDateString());
fields.SetField("FirstName", user.FirstName);
fields.SetField("LastName", user.LastName);
fields.SetField("Address1", user.Address1);
fields.SetField("Address2", user.Address2);
fields.SetField("City", user.City);
fields.SetField("State", user.State);
fields.SetField("Zip", user.Zip);
fields.SetField("Email", user.Email);
fields.SetField("Phone", user.Phone);

// set document info
System.Collections.Hashtable info = new System.Collections.Hashtable();
info["Title"] = "User Information Form";
info["Author"] = "My Client";
info["Creator"] = "My Company";
stamper.MoreInfo = info;

 // flatten form fields and close document
stamper.FormFlattening = true;
stamper.Close();
