When you stated, "would another lawyer be willing to represent me", I don't know if you meant an attorney on this site or in general. Unfortunately, the policies of Just Answer do not permit us to represent customers of this site or to provide direct referrals. However, we can point you in the right direction. And, of course, if you meant in general, then hopefully this information will be helpful.
First, you should begin with your state bar association. The Texas State Bar has a website, it is located at http://www.texasbar.com/.
I do not know your county of residence but your county bar association likely has a similar site that will be more specific to your location.
Additionally, Martindale Hubbell is a national organization that rates attorneys across the country. Their website is located at http://www.martindale.com/.
Another nationwide website is located at http://www.avvo.com/. This site lists attorneys by geographic location and area of practice.
Each of these resources will have a wealth of information as to attorneys in your area that handle such cases. I would suggest you check each site out and you will surely find a great number of attorneys that meet your needs. Pick a few to meet with in person so that you can thoroughly explain your situation and then retain the one that you feel can best represent your interests.
Having said all of that, I would suggest that you put some thought into this before proceeding. While I am inclined to agree with your assessment of the attorney having somehow mishandled the citation, I don't know that it is worth pursuing. The problem is that it would probably cost more money to change attorneys than to just stick with this one. The decision, of course, is yours to make. Perhaps you can contact a few attorneys, ask them about fees and then make a more intelligent decision as to what is in your best interests.
Also, several customers have asked how they may direct a question to me in particular. If you specifically want me to assist you in your legal matter, just put "FOR JOSEPH" in the subject line and I will gladly pick up the question as soon as I am on-line.
