These free solutions have some limitations. Most can be worked around but if they don’t do exactly what you want, you can get a site customised, & I can help finding & briefing a web developer.
Your budget will depend on how much customisation you require.
At the top end, larger organisations are often willing to invest significant time & money into sites to get exactly what they want.
