What's your budget? I've found there's two ways to go with umbrellas 1) get a really expensive one that seems to be very hardy and then a bad storm trashes it 2) go with a quality somewhat expensive one and replace the fabric part every year or even the total umbrella if you forget to drop it when snow is coming. :-) There are however, commercial grade stands and umbrellas that stand up to the elements well but they can get quite pricey. Here's a good brand https://www.tuuci.com/collections/parasols/?utm_source=google_nonbrand_expandedtext&utm_medium=paidsearch&utm_campaign=northamerica_multiplelobs&utm_content=multiproduct&gclid=EAIaIQobChMIk-b2l_ze7AIVBYTICh07bwXjEAAYAiAAEgLTjvD_BwE Knowing your budget is key

There are people/companies who do restoration of all kinds of stuff including china and ceramics. My mother had a porcelain figure which had some damage and she had it fixed by a professional restorer. You can't tell where the restoration was unless of course you are someone in the industry who is extremely savvy and looking for restoration since that impacts the value of antiques. You could start by calling a local museum and asking to speak to someone in their conservation department. Or call an antique store in your area and find out who they might recommend. It is not cheap to have it restored professionally but it generally is worth it if the piece merits the expense because it will look as good as new. You might also cross post in the Antiques and Collectibles Forum. Although it's not an antique, people conversant with antiques would probably know how to find a restoration place in your location.

For a visual, below is an 8’ umbrella over a 30” table. BUT note the seating and shade. Here is a 10’ one over a conversation grouping. About 7’ between seats.

Colored cushions would be nice..and more comfy when you are entertaining..even a fabric runner to match..to make the table a little more of a focal point..
