How long are the pieces of PVC? 10 feet? 20 feet? You need to get up and down the ladder to hang a J hook every 4 feet or so. Then hang a piece of PVC, pull a string through, glue a joint, hang another piece, pull the string, and so forth.

Do you not like icex?

Not really...one person can do it, on a ladder, with a rotohammer.

You'll need scafolding. 2 people need to be up, one at each end of the piece of conduit to hang it in J hooks. You don't want to be lifting lengths of PVC conduit by yourself 15' up on a stepladder.

Yeah it will be a all day job. To beat it all its in the middle of a thrift store (the actual building the wires is going to is a law firm but she owns the whole building) so I'll be working in the middle of people shopping.

What do you think your time and your helper's time is worth, and how long do you think this is going to take you? If the customer isn't willing to pay you what you have to have to make a reasonable profit, then it isn't worth it to do the job. You've said you think you need a full day to terminate lines into the 66 block, and you have a lot of other work mentioned as well - so it sounds like it's maybe 2 days or more (but you'll have to figure out how many hours based on what you see when you look at the job site). Also, don't forget to figure out your costs for materials (conduit, brackets, cable, etc), and then determine how much you need to mark that up as well.
