You mean all
JSP and no MVC,
Having sympathy for you, no one can really estimate the effort required to convert such project into Spring. You need to get some experienced MVC developer who got hands on experience on Spring MVC and let them decide how much (pain) effort it would require to make it Springify..

Again, if you asked me, I can't say anything unless I see code.
