If you're allergic to these spiders, and there really are as many as you say then I think you're only solution is to get someone else to clear the garden - either some good friends who are quite hardy and aren't allergic, or a garden maintenance person - there'll be some advertising in your local free-papers etc. Or some of your neighbours may know of someone local.
I wouldn't advise you to employ anyone who just knocks on the door and doesn't have checkable references.
Get a firm price of what they're going to do and what they will charge you before they start, and take before and after photos, just in case of any disputes to be on the safe side.
