Marty's missions are available at the payphone near Joey's Auto Garage and the phone rings between 09:00 and 19:00. If you can get there as early as 09:00, you may be able to complete them all on the stroke of 19:00. His missions are easy and so they don't need much detail.
The Crook
Marty introduces himself and says that he's got himself into a lot of money troubles. He has a crooked bank manager who's gonna withdraw all his money unless he gets a cut of it, but Marty has other ideas. Take his Perennial (he will always give you cheapo cars) and pick up the bank manager. Take him back to the factory and hear him get turned in a dog's chunks(well, the best way to describe it). You are then told to get to the crusher so there will be no evidence against Marty if this goes to court. Once the car is crushed, you get $1000 and a little extra money from crushing the car.
The Theives
Since Marty has low money, he's hired theives to break into his apartment and claim on the insurance "as you do". And now the guys are threatening to tell the insurance company to say that he hired them and so he would go to court if they say this unless they get a cut. He has left a Sentinel for you to pick them up. So pick the theives up from the apartment and take them to the factory where they also get turned into puppy chow. Re-spray the car and head back to get $3000 (well, $2000 since you had to spend $1000 at the Pay 'N' Spray).
The Wife
Marty's business needs to get a hold of a big lump of cash otherwise the business is going under. His wife has a nice bank balance only because she uses Marty's money and has burned a very large hole in his pocket. She's glitzing herself up at Classic Nails in the Red Light District and you will have to pick her up in another cheapo car. Head to Classic Nails and pick her up and take her to the factory - another bag full of dog treats are made here. You will have to sink the car, and head to the pier at the Callahan Point and push it in. Gravity takes over and so you walk away with $2000.
Her Lover
It turns out that Marty's wife was seeing a guy that he owed money to. He's really angry and wants to see Marty, and you will have to pick him up in a nice Stallion. Pick him up and you will see Marty talking to the guy, named Carl. He shoots him, and that ends the mission. $4000 and you will obviously not have any more jobs with Marty. Run over Carl and take his Shotgun if you want.
