Wordpress can work, there is a great variety of software add-ons to develop almost anything, but it really takes someone who is an expert in Wordpress to make it look good. There are many software packages that claim you can get a site up and running in minutes, that's not really the case for the vast majority of people unless one is happy with a bare-bones basic site. So unless a volunteer with such experience could be located, someone experienced with Wordpress would be an up-front (and on-going) expense. Some of that could be offset with affiliate ads, which would take a while to generate income, and may not ultimately cover the continuing expenses. Add the expense of any software plug-ins, not to mention ongoing host expense.
