<p>If you can ascertain an “average” rate for your area, that’s a starting point. I’d ask her hourly rate for lessons, just for reference, and compromise. The trick is to be fair to both parties, and come to an agreement where every one feels good about it, and doesn’t feel like they made out like a bandit or got shafted. You may also wsh to weigh if the actual audition will cut into her lesson schedule. You may wish to be a bit more generous if she loses some income while traveling. Just some points to consider while negotiating.</p>
<p>If $50/hr is reasonable, then I’d figure a minimum of an hour per piece, which is $300. You may well need more time, and I doubt less. Perhaps a flat fee of $500 is reasonable, up to 10 sessions, and more hourly thereafter. If her lesson rate is less or more than the average accomapaniment rate. maybe split the difference. The travel as I said is negotiable. You can trade off dinner for fares, or as BassDad a barter/quid pro quo if she made need your services for her students.</p>
