Okay, let’s calculate this. Tiffany has a broad range of skills, but they're not super high-demand in the market. Editing and research are useful, but they're not typically high-paying. Grant writing and nonprofit experience are valuable, but the rates for those skills are generally lower. Marketing and fundraising are in demand, but the rates for those skills are also relatively lower. Considering her location in San Francisco, which is a high-cost-of-living area, I'd expect her to charge higher rates. However, based on the skills she has, I think a rate of $75 per hour is reasonable, which is lower than what someone with more in-demand skills might charge.
