Producers are a big part of pop cultures POP! someone has to make the deals and guide that path for all those little rich wanna be singers and rappers! so why not give them a money sucking middle aged vampire to leech off their profits! and hey, if they go big time its a win win repeated word for everyone. Just watch out for those helicopter parents who want you to sign contracts guaranteeing this and that. I mean really, who really needs it in paper that your daughters gonna be hitting the top 20 charts in the next 2-3 years! C'mon! Allow for creating of production contracts and hiring of actor's singer's artist's and all other walks of life in exchange for speaking on their behalf to arrange shows, galleries, lead roles and eventually perpetual stardom!

Much like the real estate agent many cars come with different package options from heated interior to twin turbo and custom exhausts. Allow people to start their own car dealerships/customs shops and sell pre assembled packages for cars. maybe that Ferrari has the S-1 edition modeled after an F-1 racing car it comes with custom spoiler, engine modification, exhaust, racing coilover suspension and all for only 150,000$ more! what a deal! Allow shops of certain renown to release customs set ups that they themselves put together and assemble for dealership. Everybody wants a car custom made to their specification. Allows for the premade customization of vehicles ready to be bought right from the partnered dealership, special design and customization options for vehicles, special sponsored race vehicles and sponsorship for race teams. design and entry into game of new vehicles (if possible)

You've created such an in depth housing system but you need people who know what they are doing to set the prices for houses, manage builds/properties and set up showings and barter deals with high value clients. If HGTV taught me anything its that real estate is no joke. you need some grit and suave to get the deal! Allow players to purchase sales rights to a building. set up different options for tenants to buy into, pre furnished, unfurnished, developments, as well as business properties and land for sale. not everyone who moves to the city will have a pre furnished, established rent house to move right into!
