Welcome to the forum! Your topo looks like you have some gentle sloping that could capture some runoff. A well is always nice, but a few thousand bucks. You could also possibly use a trash pump to grab water from the roadside ditch when/if needed and it is flowing.

To start, try getting your local NRCS agent from your area USDA field office to do a site visit, take soil core samples and shoot some elevations if possible. That could give you an idea of watershed and site possibilities along with available clay....all at no cost to you.
