what sort of band are you talking about? what style? how much experience does each member bring to the table? how long has the band been together? what's the goal of the band? how much original material do you have? how many gigs has the band had in the past?
the fact that you joined an international discussion site for general music rather than indicating you tried and failed with a local scene site leads me to believe your band has a whole lot of plans and ideas but very little of anything else going on.
if you don't have a full band yet you don't need a producer. i mean really, getting a producer before a bass player is like getting a trailer for carrying all your gear for your tour that will happen just as soon as you fix the chassis on your truck.
if you don't have a way of getting any gigs yet you don't need an ep. there's a modern fallacy that it's not possible to get gigs without pro-quality demos. that's a farce. go to an open-mic night. go to the karaoke bar and OWN the stage. go to gigs at venues you'd like to play someday and make contact with the staff. most importantly establish this contact while SOBER, make it clear to the people you're talking with that you're serious about being a musician (if you actually are) don't ever toss attitude, everyone knows someone who can turn out to be THAT connection in the right situation.
you'll be amazed at the kind of doors that open up with a bit of networking. you won't be getting headlining offers at the most prestigious venue in your city to start - but no one does. the quicker you can accept this without quantifying the statement with 'b...b... but... but we're different... our band is
special' the quicker you'll actually start making the kind of small steps that actually accumulate into legitimate progress.
as for the earlier comment of forcing a guitar player to play bass - that's a fool's errand. you'll be wasting your time. yes, that person can technically play both instruments, but generally speaking it's a recipe for disaster. the guitarist will likely become resentful at not being able to play the instrument they prefer and being forced into a role he doesn't necessarily want by the people who control the band (regardless of how much they might want to call everyone 'equals'). it's a functional solution for the short term (if you need a fill-in for a recording session), but long term, it's usually not ideal.
tl/dr - get the ball rolling on a local level. word of mouth will take you farther than endless pages of praise on the internet.
