Low budget business

You can market it better, look at some successful Kickstarters for inspiration. A nice video and a website maybe.

there was a guy who sold 3d printed spacex rocket models that he painted.
cant remember how much he sold but in the hundreds i think

Honestly in Cali how realistic is it to be able to compete with Mexicans who do this.

Nice, This gave me some ideas

I suggest using your remaining money scheduling, route planning and accounting software. Efficient service delivery will put you ahead of the competition, while decreasing fuel and maintenance costs. Accounting software will keep you from paying to suck uncle sam's dick.

Can you recommend any ?

you're late the party. even you manage to white label a product that sells either amazon or another 3rd party seller will steal your source and undercut you.

ive also been thinking abount making metal casted things, by using 3d prints as kind of molds.
but seems difficult to get right

I'd need to know a little more about your business.
Burger?
Geographical size of proposed business area?
Amount of services rendered per day?
Method of transport?
