What would be a reasonable expectation to spend on design (concept, plans, approval by city... but NOT management of the construction process) VERSUS cost of the project?

We are budgeting $100K for an addition/some remodeling of existing house and have gotten a quote from the architect for $10K to prepare an agreed-upon set of drawings, submit to council for approval (and make any necessary revisions they require).

My husband thinks that is astronomical but I'm not so sure. 10%?

Can anyone give me any ideas on if it sounds reasonable or high?

The only other quote I've gotten so far was from a DESIGNER (but he lacked creativity... he was merely drawing what I requested) and it was only $1000 for the initial set of drawings. I hadn't gotten a quote from him to submit to Council for approval and do necessary revisions. The new architects quote was charging $2500 for that same part.
