Most of the belt driven cast iron compressors will do that at the expense of noise(78-80Dba) (they are 100% duty cycle though) A Ghast may be the way to go? not cheap but 5cfm at 30 psi within the duty cycle is easily possible.

Junwei are very good I use the UK version Titans) and very quiet (50 ish Dba), 16cfm at 75 psi with 120 litre tank can be had direct from china at under $800

Careful when you look at comps on the web, they often list the displacement not the Free Air Delivery, look for a FAD of 5cfm at 40psi and you won't go far wrong.

any which way you are likely going to be looking 300-400$+ to get somewhere close with no excess capacity with $800 being closer for a quiet machine or $600 for a noisier belt driven with extra capacity.

ps: avoid direct drive, they sound like the hammers of hell and run hot (wet air)
