I also may be interested in having your services for SOP development for a GLP facility. I can provide the majority of things the sop needs for the purpose, scope and procedures but my problem is I delete, redo, and am never happy with my own work.  I could instead give basic information I want included, and you write it up.
Your prices seem fair, and most case I have most of the work done.

Do you have any sort of confidentially agreement, you potentially be exposed to things that are patent pending, chemical names or analytical data.  That is a concern.
