DATA MERGING WITH PDF AND WORD DOCS

I WANT A SOURCE DOCUMENT WITH MULTIPLE FIELDS, THAT WILL POPULATE THE INPUT DATA ONTO THE TARGET DOCUMENTS, SO THAT IT ELIMINATES HAVING TO CAPTURE DUPLICATE DATA ONTO THE TARGET DOCUMENTS. VARIOUS INPUT DATA NEED TO BE POPULATED ON VARIOUS TARGET DOCUMENTS. I HAVE THE PDF AND WORD DOCUMENTS WHICH I USUALLY PRINT OUT AND WRITE INFO ONTO, BUT THIS IS TOO LENGTHY A PROCESS. I WANT TO TYPE OUT THE INFO ON ONE INPUT DOCUMENT AND HAVE THE DATA TRANSFERRED TO ALL THE TARGET DOCUMENTS. ONCE ALL THE DATA IS TRANSFERRED, THEN THE MULTIPLE PAGES SHOULD BE MERGED INTO A PRINTABLE DOCUMENT. I DO NOT HAVE THE TIME AND KNOWLEDGE TO PUT THIS TOGETHER AND REQUIRE SOMEONE TO ASSIST ME FOR A REASONABLE FEE.
