Indigent Defense attorney not doing much at all

[helpmeplease]

Should someone that is being charged with 3 felony charges (Grand theft, Recieving stolen property, and possesion of controlled substance) but, has no previous criminal record try to get the court to appoint them a new public defender right before readiness? The court appointed the person be represented by the indigent defense system, and the attorney that they ended up with hasnt shown very much willingness nor the time to understand the case, and has from day one been only really set with the whole thing just being over quickly. The co-defendants public defender has done more for both the defendants really. The attorney from the indigent defense wasnt concerned with filing any motions at all and has basicly formed their own opinion about the whole thing and represents that way in court. She doesnt try representing in the best interest of the defendant only for what would be the quickest way to end it all. At the point of rediness would it really be a disadvantage to try and get a new attorney appointed? And how would someone go about getting new counsel to represent them if they wanted to?
