Need help pricing a french drain and grading!!!

Hi everyone, I just got a call from a lady today who lives on a large lot that needs:

-an area of approximately 100ft deep by 250ft across leveled out, there are some large piles of fill in there already and she wants those flattened out and spread, AND she wants more truckloads brought in for me to spread....im new at pricing this but ive done smaller jobs before, what should i price her for, hourly or 1 fee and how much??

-she also wants a french drain installed from near her pond in the back to the ditch near the road.

How big of a catch basin would I need to install and how much do I charge per foot??

This price per foot would include ALL materials correct?? (perforated pipe, stone, landscape fabric, fill for the top...)

Any help is greatly appreciated, thank you!!!

How much fish food should I feed my fish? There's a lot of fish and the tank is kinda big?

Dude this is all site specific.. There are so many things that need to be factored in. If you don't know how or what you're doing to complete site analysis for this kind of situation. Be honest and tell them .. Hey lets get an engineer in and plan this all out.

I did that the other day.. A person cleareed out a huge area in their back yard. The system would need at least 6 more zones to irrigate the area he cleared. Except the area had a large sloap and then the sloap came back up to almost the same elevation to the beginning of the house.. He cleared the area out for the kids.

I said.. If it's for the kids a sloap just sucks.. Why not fill it in and make it as level as naturally grade as possible. Which would require roughly 250-300 yards of soil.. The guy loved the idea.

I said great- get a site design egnineer in and figure it out all for you and I'll come back and install the sprinklers . see you in two months

Agreed; I had the good luck to have a designer that never let me down. Basically, with curtain drains, it was to go to hardpan and six inches deeper, he also added surface "D" boxes that fed into the drains. It gets more complicated from there depending on the slope.
