While it is impossible to give anything approaching definitive answers to "will mark X conflict with mark Y" based on hypotheticals (search the forums for "likelihood of confusion" or even "hypotheticals" for a whole bunch of threads on point), I can say this much from your post: you would be well served to pick a new name, I believe.
Generally speaking, differing typeface or additional of graphical elements will not suffice to distinguish two identical names in similar fields. Furthermore, you already know that, in your state, at least, there exists another registered company with the same name as well.
A mark is only as valuable (and useful) as its ability to uniquely identify a single source of services. I question your mark's ability to do that based on what you've posted.
On the other hand, if you truly believe your services are significantly distinguishable from the senior users' services (or goods), then you may be able to use your mark.
