Re-deploying a Talend project for a CRM database conversion

Some time ago (early 2018) I hired someone to migrate my Act! CRM database to SuiteCRM and make some mods on SuiteCRM ... He used the "Talend"-suite to migrate the database. He migrated the database into SuiteCRM but then needed to do some mods on SuiteCRM itself to my specs. In the mean time I had to continue working with my old Act!CRM database (he took months and months for the modding and my business was running!), which meant that the migrated SuiteCRM immediately went out-of-date. No problem I thought, when the modding is finished he would just re-deploy this Talend project to update the database ... This modding of the SuiteCRM finally went wrong and the guy delivered the half-modded SuiteCRM and walked away from the project (thus I was left with an outdated SuiteCRM-database and a half-modded SuiteCRM application). Since then I found another guy to fix the mods of the SuiteCRM application, but my database is still hoplessly outdated ! So, the guy who made the original Talend migration project has vanished, I'm kinda stuck with this project ... (luckily he had sent the Talend project- and documentation-files over to me before dissapearing completely) So, I have a Talend project for migrating my Act!CRM database into SuiteCRM, but as I'm not a developer I need someone to re-deploy (and make some minor adjustments to) this Talend project to re-migrate my Act!CRM database into SuiteCRM, thus updating the SuiteCRM database so I can finally start using it ... I have the documented Talend project, and all the needed databases and export files to perform this migration (like he did in august 2018). It worked then, so I guess it would still work today, right ? I can send all these files for you to look at, and estimate this job, let me know !
