I am a professional audio engineer & musician, have been playing for 20+ yrs and have played on 200+ recordings done in Canada, Nashville, Memphis and Chicago. I can add some electric guitar, pedal steel or lap steel to your song.
Basic rate is for one verse & chorus of the tune, if you've recorded to a click track you should be able to copy and paste. If you've got other parts e.g. bridge or middle 8, variations etc. just purchase one more gig from me to cover that.
I would ask that you credit me in the liner notes/online and let me know about it if the project is for sale or is for an ad, jingle etc., just so I can add it to my resume and link to it from my page.
I will provide you with an example MP3 mix with the part I played, a 24 bit/96k WAV file of the guitar track so you can use it in your mix however you choose.
