As long as people are willing to pay you to teach yourself on their pond I say go for it.
15'x7' is a small pond imo.
Have you looked through the yellow pages, penny savers, Craig's LIst and bulletin boards at local pet shops to see what your competition is? How much they charge? How they do a cleaning? 90% of running a business is running a business. Most of it is the same whether it's keeping ponds or remodeling bathrooms. Knowing your market, marketing, business plans, cash flow, customer relations, bidding are required skills to even have a chance at success.
In many areas most pond businesses are Aquascape certified contractors. You can check their web site to see who is working in your area. Draining and cleaning a pond is a standard Aquascape method, and the depth of this pond is an Aquascape type depth. But no rocks in the bottom?
My guess is the owners called some listed businesses and got a price of $400-500 and figured they could get someone cheaper. And they were correct.
I assume you already have your trash pump, power washer, wet shop vac, waste hoses, garden hose, GFI extension cords, etc?
Generator is nice too because often a home only has a single GFI circuit outside which sometimes has to be reset from inside the house. If it trips and they're not home you're screwed.
You have a tank ready to house the fish? Net for catching the fish? Air pump? Net to cover the tank? You've discussed with the owner the danger this all is to the fish? You've agreed in writing who's responsible if the fish die? Some people really love their fish. Some people don't even know they have fish.
You have a test kit to test the new water? You know what the different parameters mean and how to adjust? Will dechlorinator be needed?
You've already discussed with the customer where you can pump the waste water? And where you can put all the smelly muck?
Maybe you could post a video of how the job goes. Future customers will like to see you working on a job.

The pond is huge and only have a small pump that is rated for about 500 gallons per hour hooked up to a waterfall box with plastic media inside of it.
Why do you say the pump is too small?

That's all they have for filtering...it's pretty bad. No wonder it's so dirty.
So i didn't want to do it but they insisted on emptying it and having me clean all the organic debree and then i'd have to cycle it back up. I have to try to do what I can with there filter and if not recomend some wort of bio filter.
You think a bio filter makes water clear? Have you already tested the water to see if a bio filter is actually needed?

But anyway I'm pretty sure I can work with it i'm thinking it'll be a day to max four day job and I think i'm going to charge something like 150 if it's two days and 45 every additional day. I'm thinking a day will be about five hours...
So you're charging by the hour, not fix bid? Customer is OK with an open ended contact of $45 per day? Sweet.
You're only going to work 5 hours a day? Sweet.
After you've cleaned a few ponds you'll find that a 15'x7' shallow pond should only take a single person about 4 hours. You've heard the expression "time is money"? It is. Of that 4 hours it'll take an hour to unload set up, pack up and clean up. If you have to do that multiple days it's money out of your pocket, unless you can find people willing to pay you for that. Most customers are smarter than that and prefer a fix bid.
Spreading the job out as long as possible increases your risks. Fish die, dog comes a long at night and decides to dig a hole in the liner. Had that happen to me once while I was at lunch. Guess who gets to pay for that? After that I fenced the pond if I was going to be off site.

...but I'm not going to guarentee anything.
How course not. Smart.

From my experience I'm going to expect that once the organic leafy debree and algae has been removed and a new more powerful pump and filter system have been installed the pond should clear up.
Doesn't really matter if it does or not. It will be very clear when you refill. That's enough to get paid. If it turns green in a week that's a separate job.

I think you're about to learn a lot. Hope you can post video, pictures and how it goes.
