All of my projects include a warranty to assure the customer satisfaction. When developing web sites, or resumes, they are intended to protect the work from mis-spellings, or code problems. Such warranties are 60 days from finalization, and does not cover adjustments or changes to content. It does cover any malformed code that comes as non-compliant, or spelling problems. Unique words that are not in the common US English language are not covered.
You can also acquire an extended protection plan. This is usually good for larger sites. An extended protection is based on the number of files, within the site, and covers all of the normal warranty issues. It however would last for 1 year. If you are interested, you would want to ask about extended warranty when you request for services.
Warranty does not cover changes to the content, nor does it cover any changes to the files, or codes. If for example, you change the dimensions of an image on your site, the warranty does not cover your mistakes. Also, it does not cover if you move to a new host, but any changes that need to be done to the code can be done at minimal costs, usually just an hour's of work. Your warranty would be renewed as long as you are not known for moving to a new host every month or two. If you are in need of hosting, I can offer basic services, or may I suggest DreamHost(go)
which I can provide a discount code to lessen that initial charge.
