If interested, please send me a Proposal in PDF report which needs to include the following:

1) SEO Audit - What topics will be covered and how many pages in PDF?
2) Performance Audit - What topics will be covered and how many pages in PDF?
3) Technical Assessment - What topics will be covered and how many pages in PDF?
4) Any info you require from me or any assistance while you conduct the Audit?

Let me know:

Feel free to ask any questions.

N.B
1) You don't need to find out functional and usability errors/issues. The Audit that I want you to perform is related to back-end, not front-end issues.
2) Solution/Recommendation not required now. Just looking for Audit Report at this stage.

Please quote me a fixed price (including how many hours of work).
