Regarding the agent/helper that assisted you....was he an actual Realtor? 

But I'd do everything I could to offer her a list of helpers to go with that cash.  

You are looking at a day or 2 of work for a mason and a helper. maybe $100 in blocks and mortar. 

Take helpers with you.Now, after 24 hours, anything left on the property becomes your personal property... that includes everything like cars, other valuables, whatever they may have left.NOT A LAWYER, NO LEGAL ADVICE!

I would be very helpful and beneficial to anybody who needs a helper or wants to expand his business but doesn't have time for that.

But I wouldn't want to defend myself to anyone about paying those fees to unaware "helpers" when you should know how to operate ethically and legally because you're in the business.

It's much faster if you have a helper hold a large 2 by 4 ft sheet of 1/4" plywood attached to a pole for very quick spraying around windows without taping anything. 

Time frame was  6 weeks mostly because I only had 1 helper on the job until I pulled my property managers team in also to finish up.  

And like I said, I do all my own work, although I'd likely hire a helper for the siding (long boards) and the roof, I'm a bit old to strip the old one but I can sure do the new one.Your list, my numbers, just guessing as I don't know any dimensions1) siding $15002) roof $$15003) 11 double-hung windows, 4 glassblock windows $2K4) clean yard $5005) repair fence $3006) replace attic windows with vents $5007) replace garage door $5008 ) install lattice around porch $3009) troubleshoot plumbing/electric, make all minor repairs $50010) LR-patch/paint, new carpet $1K11) DR-patch/paint, restore hardwood floor$1500 12) Kit-drywall ceiling, $500replace countertop and backsplash, $500install vinyl floor$500, install new door to basement $20013) Hall-install new thermostat, patch/paint walls, new closet door$200 14) Bath-???

(This would not include out-of-service units)For a property of that size, in a "deferred maintenance" state, you should look closely at hiring a full time employee and a part time helper (at a minimum) to perform basic cleaning, groundskeeping, maintenence and improvements.
