After letting 1 real estate agent go, can another real estate agent try 2 start selling it right away?

I have a major problem, please help......I signed a contract w/a real estate agent that I knew, however she did not fill in the date, but said as long as I gave her a 2 week notice, I knew it wasn't wise, but I didn't want 2 seem untrustworthy & I did feel I would stick w/her, because I did trust her, however I didn't know her @ all, she is not listing or taking pics the way I thk she should & I brought this 2 her attention & asked her 2 do it differently & she told me 2 "trust her", we r in the prime selling season, she will not take a pic of the beautiful updated large oak bathroom vanity & mirror w/pergo flooring that is off of the spacious 15 X 19 Master bedroom that has brand new hunter green carpet that I jst laid down, with newer windows & matching hunter green mini blinds, no pic of the 2nd bedroom w/new flooring as well & newer windows, no pic of the foyer w/a real tile floor & real partially bricked wall, instead she keeps in the pic of the crudy part of the basement that I told her I want removed, takes 2 pics of the new living room carpet that she picked out & took out the old pic that showed the open floor plan in this rather small house, which showed the foyer, instead she shows the gry back yard, instead she shows the dirty deck, instead she takes 2 pics of the front of the house & leaves the recycable & yard waste containers in front of the brick that goes partially up the house, these r green & blue apprx. 4' each high containers (not inviting).....I said if u only have 8 pics I wanted 2 b sure & get the master bedroom & bathroom, delete basement, I explained when I'm looking I want 2 c the inside & if they don't have pics up of the inside I'm going 2 move on, if u only have 8 pics she needed 2 utilize those on the finests selling points inside & of course u need a front view of the house, (preferably without objects) & she didn't listen @ all & basically made it worst, because now u can't c the open floor plan or the foyer, I told her I wanted her to mention the 2005 central air that I put in, but she didn't or the 2001 furnace & water heater, updated kitchen & bathroom, all of those are good selling points, all of which I told her, instead she mentions there is room to build a garage, please point out what I DO have rather than what I don't have, take pics of all the good, not the very worst crudy part in the basement.....I want her out of here now, but verbally she said 2 weeks, legally there was no date when I signed the papers.......she does work 4 a reputable real estate company, if that helps, I jst signed June 1st, but I,ve had house 4 sell for about 10 months, I need 2 move it now, also she said she could sell it in a month, it's been a month, she wanted me 2 prof. clean a carpet, I did that, not good enough, so she wanted me 2 replace, so I did, then she wanted me 2 buy used frig, so I did, I keep doing what she advises me 2 do that costs me money, why can't she do what I ask her 2 do, isn't she working 4 me, but she isn't listening, yet I signed an undated contract ....help me, please!!!
