@James Hughes Hey James, I am studying Computer Science at Fsu, and would love to work with you to make a program free of charge to send out mass e-mails, text messages etc... should be really easy as long as a file is given with the names and numbers.

And if anyone knows anything about AC systems, do you think it's appropriate to charge $180 to defrost the condenser coil?

How do they work and how much would I charge?

The couple is seemingly in their 70s and disabled, after visiting the home I'm legitimately concerned for their health and safety and feel like its my obligation to try to help.

And they'd charge you for 100 W because they estimated the meter read 13,000 at the end of July.

Especially if you charged for applying, but even if you did not, I think you should rent at your advertised rate. 

I dont really charge a deposit for mine but we try and really vet them first.

Also look at the competition in the area to see what they charge and the amenities they offer.As @Sean Delisle mentioned, do your research before buying a property.

Window world charges about $500/window installed for a bottom of the line vinyl replacement window.
