Ah - good old employee mentality
As a self employed person we have to pay for and update/replace our own equipment (cameras, lenses, computers, software), get insurances, pay for marketing, marketing and more maketing and also try to save for the quieter months when there's less work around as well as saving for retirement.
Successful wedding photographers should look to get £3-4k from their ability/art and from resulting albums, orders/re-orders which goes to cover all the above expenditure
I personally do commercial/product work, but for a change I occassionaly help as second camera for a friend that does wedding+portraits and I know that there's a
lot of pre-wedding meetings and preparation that takes place as well as post production and liasing between client, Lab, venue and so on.
It sounds like you think they turn up 10 mins before, take snaps, download and send them to boots for printing. In reality a wedding photographer will cumulatively work for 2-4weeks over a period of months for each wedding and the wedding day is often 16 hours non stop except for a couple of sandwiches
The only easy money in photography is when a client cancels last minute and you keep the deposit, but then you'll already have spent time on their project/session as well as holding a space in your schedule and turning other work away fro the same time, so that's only fair.
I'm not having a go, I'm just (hopefully) giving you more information which may re-adjust your perspective on what you get when you hire a pro.
I'm sure someone will take you up on your offer, but business owners will cast their opinions because the money offered is not going to get a professional.... which is fine. You know what you want and how much you're willing to spend and that's that
This will be an oppertunity for a student or someone new to have a play and get a bit of cash in hand, but when you hire a professional to take your pictures of the day think of it as hiring a company rather than just one person
