Like Mike said you need to ask what file format they want it in. Once you know that there are free programs, like
IrfanView, that you can download and will convert the image you currently have to the format they want.
If you find out what they want (file format) post back and I'll check if IrfanView can convert to it. If worse comes to worse you can PM me and I'll send you my e-mail address and if you send me the image I'll convert it and send it back to you.
Edit: It looks like
MikeN (in the next post) knows a lot more about embroidery digitizing so I'd follow his advice. If was as simple as converting the file format they wouldn't be charging as much, if anything, to just do it themselves.
