Hello,
by means of introduction, I'm Prakash. I'm a senior software engineer at Rooh. My team has DBAs and SDEs who are proficient in dealing with database design, implementation, migration and maintenance.
Looking at the project description you've provided, "database based project to link up with an existing database", it is not very clear to me what the ask here is. Are you looking for database migration? Are you looking to hook up a new database to your existing application and have it work with both databases?
I'd really appreciate it if you could please provide bit more specifics about the work involved. Once we've a better idea of the work, we can provide you solution proposals and a better estimate of effort and cost.
Please feel free to email me at prakash at roohindia dot in. I look forward to hearing from you.
Regards,
Prakash
