"Rubbish" is all relative. If you define a good photo as "life like", crystal-clear, high contrast, with nice saturation, then yes... in your opinion.. it is rubbish
To the artists that enjoy polaroids, old film, cross-processing, and the not so perfect photos of an Holga... they are not. One of the handful of photos I actually "sold" for money was from a misbehaving polaroid... which many would consider rubbish.
For me.. rubbish is defined as an object that doesn't meet ones expectations by a long shot. These are cars that break down from the time they leave the lot. These are high class expensive restaurants that have horrible service and crappy food. These are stores that refuse to take back returns. For those making 6-7 figures, McDonalds might be considered rubbish food... for me I like it on occasion. If the original posters photography business meets his/her client's expectations.. then his service is NOT rubbish. no matter how low he charges.
My point is that cheap != rubbish.. not even close. Keep doing what you are doing "jols" and ignore what others say... listen to your customers.
I'm sure we can find couples enjoying their memories from a Las Vegas quickie cheapo wedding.... if not.. the chapels wouldn't still be in business. I"m sure those couples wouldn't classify their "wedding" as rubbish.
