Sending a pdf to have signed from someone else

I work for a company and want to be able to send the pdf's to my co-workers and have them send them out to their customers to have signed. I know there is the sign and fill, however I want it to be a electronic signature like when you send the PDF to get signed and it automatically fills an area. I've created a PDF that has signature's and initial fields, but it seems it only work if I send it through my adobe pro. Is there any way I can send the PDF to someone and they send it out themselves and have the customer electronically sign or can it only go through my adobe?

Thanks in advance!
