@Ron A. You don't need an architect and full set of plans for a zoning variance. You will need those later if the zoning variance is approved and decide to get building permits.
Typically you just need to show a site plan and present your plan to zoning/the community. It may help to get say, an environmental report to ease any concerns zoning or the community may have but usually isn't the case with a smaller project.
Get a site plan and some renderings and present it to zoning and see what other suggestions they have. All for a grand or less.
I've worked with several architects, as long as they are familiar with the municipality's rules, and your project doesn't have some type of special focus (obviously they should have previous experience with your type of project), they will generally be fine. BUT their prices will vary wildly and usually there is no justification for the huge markup. If you want to save time simply submit your plans earlier and save 30k. No brainer.
